They did lunch!

A relaxed-looking Chelsea Handler and 50 Cent stepped out together in Malibu on Sunday. After a one-on-one lunch, the comedienne and rapper, both 35, drove off in his massive Rolls Royce.

It's the third time in October that the odd pair were spotted enjoying one another's company.

Early last month, a source told UsMagazine.com that the duo have been casually dating for "a while. It's more of a hookup thing -- whenever they are in the same town."

Both single stars have been coy about anything romantic between them.

"Everyone, calm down," Handler Tweeted Oct. 6 after she was snapped getting cozy with the rapper (real name: Curtis Jackson III) in New Orleans. "There's nothing to report yet. I'll let you know if there is."
