The hip-hop superstar became pals with the Hollywood A-listers in 2008 after he appeared with them in movie 'Righteous Kill' and enjoys meeting up with them because the attention is taken away from him.
He said: "It's interesting being around them because when you are around someone that has that much attention focused on them, I get the chance to be a regular guy on the side, so it's kind of cool to hang out them."
Earlier this week, 50 was forced to pull the release of his new album.
The 'In Da Club' hitmaker claims problems with his record company, Interscope, have prevented him from being able to release the album - which had The Working Title 'Black Magic' - and vowed not to work with them again.
He tweeted: "Man I'm not releasing a album i can't believe interscope is this f***ed up right now. I apologize to all my fans (sic).
"I will work with other artist on there projects but I will not put out another album. They dropped the ball with me one time to many (sic)."
