Sumner Redstone has been sharing almost as many meals with Tom Cruise as he has with his girlfriend Christine Peters, and now all three are dining together. The Viacom/CBS boss broke up with Peters shortly before he married Paula Fortunato in 2002, and fired Cruise after he jumped on Oprah Winfrey‘s couch in 2006. But now Peters is dating Redstone again since his divorce last year, and Cruise will star in “Mission: Impossible 4” for Redstone’s Paramount. The three dined last week at Il Piccolino in Beverly Hills. Maybe a new project is in the works under Peters’ banner, CFP Productions, which had a big hit with “How to Lose a Guy in 10 Days.”
