Gwyneth Paltrow's Slips A Side Boob In Ill-Fitting Dress

Gwyneth Paltrow was looking a little overexposed in an ill-fitting white dress that showed off some sagging cleavage at the weekend.

The Iron Man star treated onlookers at the Fontainebleau Miami Beach Hotel opening party to a glimpse of her unsupported bosom, which seemed to be in danger of slipping out from under her corset-style dress .

Other A-listers to attend the ultra-chic hotel resort party included Kate Hudson, Paris Hilton and Mariah Carey.
