Cameron Diaz and P Diddy all over each other at Golden Globes bash

Cameron Diaz

The pair were spotted kissing in front of a crowd.

Actress, Cameron Diaz seems to have re-winded to her teenage years - after hitting up a post-Golden Globes bash at Sunset Tower on January 15 acting like a teenager with rapper, Sean Diddy Combs.

The Bad Teacher star - who looked like she was reliving her teenage years - was overheard telling pals: "I have the best ass for someone who's 39!"

Cameron - who is rumoured to be the rap stars girlfriend - has had on-and-off hookups since 2008 with the music mogul.

A source told US Weekly on Friday, that just two days prior, the blonde beauty "was straddling him" at the CAA gala at Soho House in West Hollywood.

A source revealed: "Her hair was all crazy, her makeup was smeared and they made out in front of everyone.

"She was acting like a teenager!"

Camerons representative has denied the pair were kissing.
