Chris Brown and Karrueche Tran's dating life is reportedly shaky due to his ex Rihanna, as the "Turn Up the Music" singer shows off his sexy model girlfriend through his social media account.

According to Hollywood Life, which talked to an insider, there's no truth to the tension in Chris Brown and Karrueche Tran's dating relationship.

"Karrueche is one of the main reasons Chris is back on his feet and becoming more mature as the days go by," the source said. "He wouldn't break her like that. He loves Karrueche too much and wants her in his life forever. Especially on a romantic level."

"In Chris' mind, not too many girls can replace Karrueche or even walk in her shoes. He has promised her he'd never cheat on her or break her heart again and he meant that," the source said, adding that the singer and the model "are solid."

The comments came in the wake of the report of Chris Brown and Karrueche Tran's dating life being shaky after the singer confessed to Entertainment Weekly that he's started communicating with ex Rihanna again.

The website also pointed out that the song "Drunk Texting" is a message to Rihanna, which Chris Brown quickly denied.

"I think that's just the fans' perception or the media's perception at all times because of our history," he said, explaining that every song he writes is not about Rihanna. "At the end of the day it's almost six, seven years later. It's like, how many more times am I going to talk about the same situation?"

When asked about their relationship, Chris Brown explained of Rihanna: "We're friends. Nothing too serious... We're not trying to start a life together right now, we're just having fun."

Perhaps to make amends, Chris Brown posted a sexy photo of girlfriend Karrueche Tran sitting on a chair on the beach with her knees up showing off her tanned legs, said MailOnline.
