Kelly Brook's friendship with Jeremy Piven is set to boost her acting career.

The brunette-beauty 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 revealed to The Sun newspaper: ''Kelly and Jeremy were reciting lines at his place. They hung out then he helped her prepare for her audition.''

However, Kelly's friendship with the 48-year-old hunk - famed for his role as Ari Gold in the TV series - 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 film 'Piranha 3D', but she is yet to achieve mainstream success.

The 33-year-old TV personality has denied claims she is dating Jeremy, following her split from rugby star Danny Cipriani.
