Kelly Brook's friendship with Jeremy Piven is all about bolstering her acting career. Who'd have thought it.

The brunette had been spotted looking cosy with the Entourage star at his Malibu mansion last week and it's alleged the pair have been spending time together in order to "prepare" her for a lead role in the film-adaptation of the hit US series.

A source having the bants with The Sun offered: "Kelly and Jeremy were reciting lines at his place. They hung out then he helped her prepare for her audition." It was lovely, there were bouncy couches everywhere!!

Despite Kelly's "friendship" with the 48-year-old hair plug enthusiast - famed for his role as Ari Gold in the TV series - it may not be enough to land her the role of the female lead as she is facing stiff competition from American model Kate Upton.

Kelly has previously tried to launch her Hollywood career through a string of acting roles in films such as 2010 "horror" Piranha 3D, and let's not forget the film featuring Keith Lemon, but in spite of whipping out the goods and debasing herself she is yet to achieve mainstream success.

The 33-year-old "actress" has denied claims she is dating Jeremy, following her split from rugby star Danny Cipriani. Who I thought she split from years ago.
