The odd couple first met when movie star Wahlberg was starting out as a pop singer and Diddy was an intern at Uptown Records - and now they're two of the biggest players in American culture.
The Fighter star Wahlberg insists he has no plans to return to music but he is hoping to work with the rap mogul and entrepreneur on a series of new film and TV ventures.
He tells WENN, ""We have a bunch of other things we're working on. He's actively pursuing an acting career in film and television, so we have some other business interests together. We've been friends for a long time.
""We started out around the same time. I met him at Uptown Records working for Andre Harrell as an intern and we've known each other forever.""
