Chris Brown is living with Karrueche Tran again, TMZ has learned. Sources told the site that Tran had been staying in the "Don't Wake Me Up" singer's house in Hollywood Hills since his 24th birthday on May 5. The 23-year-old model still kept her apartment but already moved most of her clothes and personal belongings into Brown's residence.

After splitting from Rihanna, Brown was rumored dating Tran again. Brown reportedly unfollowed Rihanna on Twitter and followed Tran. They were spotted partying at Brown's 24th birthday bash and spending a lot of time together at an after-party for Billboard Music Awards.

Brown dumped Tran for Rihanna last October. He said that choosing between Tran and Rihanna wasn't easy. He previously said, "When you share history with somebody, then you tend to fall in love with somebody else, it's kinda difficult. Is there such a thing as loving two people? I don't know if that's possible, but for me, I feel like that."

Tran and Rihanna weren't the only girls in Brown's life. A few days ago, Brown was rumored dating Topshop heiress, Chloe Green, after they were spotted spending time together. Green, who was previously linked to Jennifer Lopez's ex-husband Marc Anthony, was reportedly "having a lot of fun" with Brown.

"After he split with Rihanna and she split from Marc, they've been spending more time together and having a lot of fun. It's early days, but they've not been shy about being seen out at the same places," a source said.
