Now that Robert Downey Jr. has conquered his addiction demons and climbed back onto the A list with Iron Man, he's turning his attention to the world's real problem: no, not North Korea, but Guy Ritchie's love life. The poor bloke is single, so the star of Ritchie's upcoming Sherlock Holmes is determined to do something about that travesty.

"Robert is determined to find Guy his dream girl,” a source told the National Enquirer. “He and his wife, Susan Levin, put together a list of worthy women for [Guy] to pursue."

Guy, who has been single since his marriage to Madonna dissolved last year, has reportedly dated Elle McPherson and Hugh Grant's ex, Jemima Khan, in the meantime, but RDJ thinks Cameron Diaz or Jennifer Aniston would be fitting paramours for his pal. During the filming of Sherlock Holmes, "Robert kept telling Guy that what he needed was a new girlfriend to help him forget his troubles. But Guy wasn't ready then." How To Rebound After a Divorce

Now, though, Robert is proving himself a truly legendary wingman. "When Guy and Robert see an attractive woman, Robert introduces himself and follows up with, 'Have you met my friend Guy? He is wonderful!'"

We bet it sounds a little different, something like, "Haaaave you met Guy?" which would make Robert the Barney Stinson of Hollywood—actually, we can totally see that, because he looks dashing in a suit—so however Downey wants to go about hooking his pal up, we do not object. They seem like they'd be awesome to have a pint with and shoot the shaz.
