P Diddy writes rom-com for Sienna?

P. Diddy is writing a romantic comedy for actress Sienna Miller, say reports.

According to the Daily Star, the rapper started planning the project after his recent visit to the Cannes Film Festival.

"I’m writing a film, a comedy," said Diddy. "For actresses, I want Angelina Jolie and Sienna Miller. For actors, Eddie Murphy."

A friend of the hip-hop star added: "This is going to be one hot movie. We’re all like, 'You writing this so you can just hang with Sienna?'"

Miller was romantically linked to Diddy in January last year after they were spotted together at a nightclub in Utah.
