Cameron Diaz Calls Out Tom Cruise Over Head-Touch Challenge on 'Jimmy Kimmel Live' (VIDEO)

Apparently, Cameron Diaz and Tom Cruise are developing a bit of a competitive feud, even if he doesn't know about it. Diaz revealed on 'Jimmy Kimmel Live' (Weeknights, 12AM on ABC), that she's "just below him on the leaderboard at 'Top Gear' in England. He beat me by like a second."

But while Cruise may be able to claim victory in the UK, it was Diaz who claims the record of head-touching on Jimmy Kimmel's show. She absolutely smoked Kimmel's record, and stands at three heads over Tom Cruise -- man, that sounded like a short joke, but it's not ... Honestly!

The competition has the celebrities running around on the street outside Kimmel's studio touching people on the head. "This is much more impressive than [Top Gear]," Kimmel said.

"I'm calling him out," Diaz declared. "Tom. Buddy. Guess what? I'm three up on you." The gauntlet has been thrown. We may need a head-to-head, so to speak, showdown to settle this once and for all.
