Reign 'em in, Mariah!

You can't hold good cleavage down and Mariah Carey's bust was literally bustin' out Saturday night at Catch in West Hollywood. The diva wore a black bustier that could hardly contain her fun bags and fans got an eyeful as the sexy chanteuse left the restaurant.

Recent reports claim Mariah and ex-hubby/baby daddy Nick Cannon may be reuniting, while other rumors claim the two are just good friends and really successful co-parents. On Friday, Mariah shared a throwback pick of her and ex-boyfriend, backup dance Bryan Tanaka, sharing a milkshake together -- she captioned it, simply, #fbf." Could she get feeling nostalgic for her hot, 33-year-old boy toy?
