Chris Brown has met up with his ex-girlfriend Karrueche Tran.

The R&B star was spotted out and about with the model in Los Angeles on Monday (22.10.12), despite having ended their relationship last month in order to rekindle his romance with his former love Rihanna.

According to, the pair left his house together before driving away separately. However, they met up later on and were spotted sitting in the same car, reportedly on their way to a studio in Burbank.

The news may cause trouble between Chris and Rihanna, who told friends she felt like a ''princess'' during their romantic date on Saturday night (20.10.12).

The 'Diamonds' singer stepped out to attend the launch of his new desktop channel Qubeey in Los Angeles where they were seen hugging and kissing.

A source said: ''[Rihanna] had fun being with Chris. She loves him and anything she can do to support him she will. She wants to be by his side and show up for him and last night she did.

''Chris was real soothing - he made Rihanna feel like a princess just by the little things he was doing. He opened doors, pulled out her chair, you know, being charming Chris. He was being a gentleman and it was cute.''
