CHRIS Brown has officially been dumped.
The singer, who used to go out with Rihanna, was ditched by girlfriend Karrueche Tran this week.
Sources have told TMZ that before the split "she was unhappy for a long time".
"Chris acts immature, like a child. She thinks he's ruining his life by spending more time partying than making music," they added.
The US site were also told that Karrueche has changed her number so that Chris cannot contact her.
Days ago, before the break-up rumours surfaced, he was snapped hanging out with Kim Kardashian's little sisters - Kylie and Kendall.
Posing in a series of photos, the darlings of reality TV looked like were having the time of their lives cosying up to the rappers.
Chris - who was recently released from jail - looked like he was having the mother of all parties.
