Chris Brown's ex-girlfriend Karrueche Tran may have been romantically linked to Entourage actor Jeremy Piven, but a source close to the model insists that they are not an item.

The rumourmill first went into overdrive earlier in June when a source told Star Magazine that the stars had been flirting.

"Karrueche was gushing about Entourage, and Jeremy was clearly loving the attention," the insider explained. "She just wants to have fun. Jeremy is perfect."

But a pal has since set the record straight on the alleged romance telling Hollywood Life that while she enjoys hanging out with him, he's "not her type".

"She's a natural flirt and so is he, but that's it. Karrueche is definitely not interested in dating Jeremy," the pal added.

Although romance rumours continue to circulate , an insider claimed that Piven, who is best known for playing Ari Gold in the comedy series, is simply helping Tran break into Hollywood.

"She's trying incredibly hard to make it as an actress and he has given her some advice," the insider added.

In March, Tran ended her on and off five-year relationship with Brown after finding out that he had fathered a baby girl with another woman.

"Listen. One can only take so much. The best of luck to Chris and his family. No baby drama for me," she told her 607k Twitter followers at the time.

Weeks later, she broke down while discussing Breezy's relationship with Rihanna, his infidelity and their unhealthy break-up to make-up cycle during her televised interview on Iyanla: Fix My Life.

"I feel hurt because the man I loved betrayed me. I will never again let a man disrespect me. I want my voice to be heard... I want to clear it up and tell my story and tell my side," she told the life coach

Tran, who plays the role of Vanessa Ivy in web series Vanity, recently revealed that acting has helped her deal with her relationship woes.

"It helps to block out all the noise," she told "When I have all this drama going on in my personal life and, unfortunately, it's all over the media, I can just work and put my time and energy into that. You can't go wrong with working hard."
