P. Diddy is Cameron Diaz's "booty call", according to a report.

The Hollywood actress and music star have been spotted spending a lot of time together over recent weeks.

Cameron Diaz ended her relationship with Alex Rodriguez earlier this year, but she hasn't been stuck for male company.

P.Diddy and Cameron have had an on-off relationship since 2008.

"Since then, when she's single, she'll booty call him," an insider told US Weekly.

Reps for both stars say that the pair are "just friends" and have been meeting to discuss a possible comedy film project.

However, the duo certainly appear to be more than friends.

On October 24 Cameron and Diddy were sat in a booth at New York's Catch restaurant and then two weeks later at lunch in Scarpetta, Beverly Hills.

The pair looked "inseparable - they had their hands all over each other," an eyewitness said.
