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.
