The duo dated for a few months before Brown famously reconciled his relation with singer Rihanna. However, he is said to have kept in touch with Tran.
"I don't know if he's in love with Karrueche, but he loves her. Being in love with someone is different than loving them," hollywoodlife.com quoted a source as saying.
"He's just trying to look out for her as best as he can right now. Chris has a soft spot for her, but that's about it these days," the source added. Meanwhile, the relationship status of Brown and Rihanna is unclear.
