Chris Brown has Rihanna on tour and Karrueche Tran on speed dial.

Chris Brown is reportedly still texting Karrueche Tran.

The 'Don't Wake Me Up' singer – who is currently performing in Europe as part of his 'Carpe Diem' tour – has allegedly been in contact with his ex-girlfriend recently despite being joined on the road by Rihanna.

A source told "They talked and he did wish her a Happy Thanksgiving and they've been sending pics back and forth."

The insider revealed that the model wasn't concerned by reports that Chris spent the US holiday with Rihanna in Germany and is hoping to see him when he returns to Los Angeles for Christmas.

The source said: "She's not tripping on Rihanna being out there with Chris, she's happy for him and has his back when he gets home."

Chris – who deleted his twitter account on Sunday following an argument with another user about his domestic abuse charges - dated Karrueche for a year but dumped her last month and claimed he wanted to work on his friendship with Rihanna.

The 'Diamonds' singer – who recently claimed she and Chris are just friends – joined the 23-year-old singer on his tour in Berlin, Germany last week and the pair were all over each other at Adagio club after his gig.

Friends close to the on-again/off-again couple said he was thrilled she decided to support him on tour.

The insider said: "Chris knew Rihanna was coming and he appreciates her supporting him on another level. He missed her and he needed her to come to Berlin and chill. They are there for one another no matter what. They hit up a club just to relax. Chris was mad happy to have Rihanna there by his side."
