What goes on in Vegas most certainly will NOT stay in Vegas here!
Watch it go down (below)!!!
We can So So Def see Mariah Carey's nipple!!
Giiiiiirl, don't you know how to mind your cleavage this late in the game?? You're a pro at this!!
You DO look fab in that dress, we can't lie! It's just a shame we can totally see some areola peekin' out the top (see below) — which is right at Jermaine Dupri's eye level (because he's so short)! LOLz!!
The all-star concert was put on to celebrate 20 years of hip-hop record label So So Def in Atlanta over the weekend, and she wasn't the only mega-star there either! She shared the stage with Usher and Jay-Z as well, and we're sure even the non-famous got an eyeful too!
It will be all right, though, Mariah! These things happen, and you totes have nothing to be ashamed of!
