Paris Hilton on National Geographic cover!

It looks like a typical National Geographic cover with the signature yellow border. So what's Paris Hilton doing on there?

The folks at Harvard Lampoon persuaded employees of one of the most respected magazines to help them ensure their April Fool's parody - with stories on Mongolia's wildest waterparks and Native Girls Gone Wild - looked authentic.

The issue, coming out on Tuesday, is the latest in a string of Harvard Lampoon magazine parodies.

But the undergraduate group had never done National Geographic, which quickly responded when contacted by the students last summer.

"My guess was they were just extremely bored and they were tired of working with animals and scientists and wanted to hang out with college students," said Hayes Davenport, who edited the magazine with fellow Harvard senior Ross Arbes.

Davenport said other publications have helped with their parodies in the past, such as when USA Today printed the Lampoon's version on its press in 1989.

And he said National Geographic's staffers - who had no editorial control over the parody - were eager to make fun of their ultra-serious image.

The magazine helped print the parody and distribute it alongside its own April edition in some areas, Arbes said.

A designer also helped lay out the parody to make it look as much like the original as possible.

"They provided things that were really valuable to us," Arbes said.

Editors from National Geographic could not be reached on Monday, but the magazine released a facetious statement.

"Editors are unavailable for comment, having left the country ... as usual," it said.

Van Halen scraps more shows amid mystery ailment

NEW YORK (Billboard) - Rock band Van Halen's reunion tour fell into disarray on Monday when it announced it would postpone all shows through April 19 while guitarist Eddie Van Halen undergoes tests for an unspecified medical condition.

The news came a week after the group postponed four shows for the same reason.

Seventeen shows are now affected, beginning Tuesday in Charlottesville, Va., and running through April 15 in Baltimore, which was one of the four postponed last week. The next scheduled show is set for April 19 in Las Vegas.

According to organizers, Van Halen, 53, who has battled cancer and substance abuse, "is currently under doctors' care" and will "continue medical tests to define a course of treatment." No further details were made available.

Fans are being asked to keep their tickets, which will be honored at makeup dates to be announced.

Van Halen returned to the road last fall with original lead singer David Lee Roth for the first time in 20-plus years. The tour, which features Eddie Van Halen's teenage son Wolfgang on bass in place of co-founder Michael Anthony, has routinely sold out North American arenas.

Jessica –- I'm So NOT High-Maintenance

Jessica Simpson is flogging reports that her trip to Kuwait to visit the troops is a big production.

Her rep tells People that Jess flew commercial and that she is in fact staying in the barracks with the troops. What's more, she denies that her trip is more of a fly-by than an actual visit: "She's been with the troops all day. She's had her meals with them."

As for reports that she had a full-scale beauty battalion with her, the rep says that super-stylist Ken Paves isn't with Jess, and that she has "significantly scaled back her entourage."

Justin -- Brit's Just a "Madonna Wannabe"

Justin Timberlake didn't keep his stick in a box on Monday night, when he jabbed at ex-galpal Britney Spears at the Rock and Roll Hall of Fame ceremony.

"The world has always been full of Madonna wannabes," said JT as he introduced the Material Mom, an inductee, reports Us. "I might have even dated a couple." Day-um. He also zinged, "She has still found time to kiss someone I may or may not have publicly kissed myself while I was in the audience. Of course you know I was talking about Sean Penn."

Britney Spears' lawyer says K-Fed can pay own bill

If Kevin Federline can afford to tip a waitress two grand, he can pay his own legal fees, say lawyers for Britney Spears. Monday in a Los Angeles court, K-Fed pleaded poverty, saying his ex-wife should continue to pay his hefty law bill — $405,000 to be exact. In just four months, the acrimonious exes have racked up over a million dollars in lawyers' fees, all of which Brit is currently responsible for.

But Stacy Phillips, Britney's newest legal eagle, says that the once down-and-out Federline is more than capable of paying his own bills. "He needs to take responsibility for the diligent work being done on his behalf," she said.

Phillips told the court commissioner Federline should pay between $150,000 and $175,000 and claimed he omitted his $200,000 spousal- support checks from his earning declarations. Phillips also argued that Federline recently tipped a waitress $2,000 on a $365 bill, and has blown $20,000 on jewelry, phone calls and food while listing the charges as "business expenses."

Mark Vincent Kaplan, lawyer for Federline, says that Britney should not only keep signing his checks, but that the singer is actually getting a bargain. Said Kaplan: "If the court does not order [her] to pay, there cannot be a legal playing field. Our fees are far under the market level for the package you get."

He may be right. Spears' old law firm, Trope and Trope, charged her $630,000 for four months' work, while Federline's bill from Kaplan was about $250,000 less.

Spears didn't actually attend the hearing — her dad, Jamie Spears, executor of her estate, made an appearance. The pop tart may have been home preparing for her upcoming foray into television: CBS has confirmed that Spears will be a guest star on an episode of "How I Met Your Mother" this season.

Seeing Double: Are Celebrity Twins Hollywood's Latest Trend?

Jennifer Lopez, Nancy Grace and Marcia Cross have more in common than just being famous women at the peak of their careers. They have all recently become the proud mothers of twins.

Lately, Hollywood just can't seem to avoid the twin phenomenon and two more expectant leading ladies are rumored to be joining the club. This week, the National Enquirer reported that Jessica Alba is expecting twins with boyfriend Cash Warren, while Star and X17 Online have both claimed Angelina Jolie and Brad Pitt are expecting two additions to their ever-expanding brood.

The "celebrities having twins" trend seemed to gain momentum in 2004, when leading lady Julia Roberts, at the age of 37, gave birth to Hazel Patricia and Phinnaeus Walter Moder.

But Roberts and her husband, Danny Moder, weren't the only celeb parents with two diaper bags that year. Another Oscar winner, 44-year-old Marcia Gay Harden, welcomed a boy named Hudson Harden Scheel and a girl named Julitta Dee Harden Scheel.

Meanwhile, Dixie Chick Martie Maguire, 34 in 2004, gave birth to Eva Ruth and Kathleen Emilie. And 48-year-old Geena Davis gave birth to twin boys - Kian William and Kaiis Steven.

In 2007, the trend gained even more momentum.

Patrick Dempsey, of "Grey's Anatomy" fame, and his wife, Jillian, had twin boys too - Darby Galen and Sullivan Patrick. "Desperate Housewives'" Marcia Cross and her husband, Tom Mahoney, welcomed girls Eden and Savannah. And Garcelle Beauvais-Nilon and husband, Mike Nilon, welcomed Jax Joseph and Jaid Thomas.

Surrogacy seems to be a popular trend for celebrity parents, and having twins is often a likely outcome if several embryos are placed during in vitro fertilization. Dennis Quaid and wife, Kimberly Buffington, welcomed Thomas Boone and Zoe Grace through a surrogate. The twins were involved in a horrific blood thinner medication mix-up at the hospital soon after their birth.

Talk show host and former prosecutor Nancy Grace joined the twins club through surrogacy as well, bringing babies John David and Lucy Elizabeth into the world alongside her husband, David Linch.

And finally, just this past weekend, Jennifer Lopez and Marc Anthony welcomed their little boy and girl.

But having twins isn't just a new trend in Hollywood obstetrics. Plenty of stars themselves are twins.

The most famous twin celebrities today might be Mary-Kate and Ashley Olsen, but there are plenty of other stars who shared a womb including actors Jeremy and Jason London, and Gunnar and Matthew Nelson, of the 80's rock group Nelson.

Good Charlotte rockers Joel and Benji Madden are twins. Pop star Aaron Carter (brother of Nick) has a twin sister Angel, while Alanis Morissette has a twin brother, Wade.

Dylan & Cole Sprouse from "The Suite Life Of Zack and Cody" are twins too.

Some other celebrities with twins: Jill Hennessy and identical twin Jacqueline, Scarlett Johansson and fraternal brother Hunter, Giovanni Ribisi and twin Marissa (she's married to singer Beck), Vin Diesel and fraternal brother Paul, Joseph Fiennes and twin Jacob, Eva Green and fraternal sister Joy, Jon Heder and identical twin Daniel, Marilu Henner and twin Crystal, Ashton Kutcher and fraternal twin Michael, Isabella Rossellini and twin Ingrid, Kiefer Sutherland and twin Rachel, and Gisele Bundchen and fraternal twin Patricia.

Malfunctions in the dress makes Paris Hilton Topless

Paris Hilton unintentionally gave clubbers a quick glimpse of her twin assets, by slipping out of her dress while partying at a nightclub.

The socialite visited Boston's Estate nightclub to celebrate winning the Woman Of The Year 'award' from Harvard University's Harvard Lampoon Magazine.

But, while stepping up on stage to belt out her previous single, Stars Are Blind, Paris put on a rather eye-popping show.

"Paris certainly knows how to put on an eye-popping show," The Sun quoted an onlooker, as saying.

"It was all a little cringey as she belted out her single as she danced on stage, but the highlight was definitely seeing Paris' boobs.

"It made the entrance fee good value for money in the end!" the onlooker added.
