Karrueche Tran gets blonde while Chris Brown, Rihanna rekindle friendship?

According to HollywoodLife.com, sources close to Brown says after 90-days in rehab, Brow is so grateful for the support from his mother Joyce Hawkins, girlfriend Karrueche Tran, and ex-girlfriend Rihanna.

"He's real grateful and thankful that he has some of the strongest and most loyal women in his life. He wouldn't be where he is today, a grown and changed man, if it wasn't for his mother, Karrueche and even his ex-girlfriend [Rihanna], who he's not talking to right now. He gives props where props is do and he's learned many valuable lessons as a result of having those three special women in his life at one point or another."

Before Brown's release he opted to stay in rehab a little after his was officially allowed to leave the facility.  According to E! News sources, the R&B singer made the decision, "It was his choice," the source added, "He will come out soon."

The singer is now out and ready to start working on his upcoming music videos for his singles that are set to be released soon, but has yet to be seen with his girlfriend, Karrueche Tran. Fans asked Tran is she has reunited with the "Fine China" singer after posting Instagram photos of her blonde look and movie date post, but did not confirm if she has been around Brown yet.
