Karrueche Tran, Chris Brown Done: Frank Ocean Steals Models Heart During Grammy Wins, Chris Cries To Rihanna

Karrueche Tran is over Chris Brown after ditching her for Rihanna. Singer, Brown humiliated the young model and his business partner after he was coupled up with Rihanna at the Greystone Manor until word of Tran's arrival at the popular nightclub forced him to leave through the back door of the club with his old/new girl Rihanna.

Tran has always supported Brown and admitted to loving him and never having hard feelings against him, but those feelings seemed to have changed once Rihanna went public with their relationship in "Rollingstone" magazine. Knowing that her ex-boyfriend had gotten into a fight with singer Frank Ocean, she immediately chose sides the night of the Grammy's when Ocean took home the Grammy for "Best Contemporary Album," beating out Brown. Tran tweeted, "Congrats to @Frank_Ocean on his Grammy awards!"

Tran may still be bitter of losing the Chris Brown battle, being dragged into a love triangle, and being ignored at the same party they've attended together. A source says the pop star was seen with the Barbados beauty and headed out on a club date, "Rihanna kicked it with the girls all day yesterday and later, after the game, she hit Chris up and they talked and planned on rolling out to Greystone." The source added, "But she stopped by the club for hot minute, had a drink with Chris then she hit it. It was just a quick meet up after she'd been in the house and working and watching the game with girls."

After Rihanna attended a court hearing to support her lover over an alleged parole violation from his Domestic Violence dispute in 2009, Tran tweeted, "When you ain't sh*t, it shows."
