It was all good just a week ago … or was it?

Chris Brown and his now ex girlfriend Karrueche Tran were spotted at Compound nightclub in Atlanta last Saturday night (Sep 29) after the BET Hip-Hop Awards — exactly 5 days before he publicly dumped her on the Internet.

Though they arrived side-by-side, if you look closely, you can clearly see the distance between them. Notice how Karrueche is holding her friend’s hand — instead of Chris’ — as they’re walking in the club.

And once they got inside, Chris ditched her to get drunk, hang out with his celebrity friends and tend to his hosting duties, forcing poor Karrueche to sit on the sidelines with her friends.

Judging by the sad look on Karrueche’s face in the pics, it makes you wonder … did Karrueche already know she was on the chopping block?

Other celebs spotted at the party were Diddy, Wiz Khalifa, Flo Rida, Fat Joe, Miguel, Young Jeezy, former NBA star Allen Iverson, and Mimi Faust & Benzino from “Love & Hip-Hop Atlanta.”
