MMA Star Joe Schilling -- Ronda Rousey Would Kick My Ass!!

Add one more person to the list of people who think UFC Women's champ Ronda Rousey could beat a man ... 'cause fellow fighter Joe Schilling says the pint-size punisher would totally kick HIS ass.

Joe was out in L.A. getting ready for his upcoming scrap at Bellator 136 on Spike-TV Friday when we asked if he thought he could take out Ronda (who's nearly 50 pounds lighter) in a real-life battle of the sexes.

"I think if I fought Ronda Rousey she'd probably Judo throw and submit me at some point."

Schilling says he ain't just spitballin' either ... he says he knows Rousey personally and she's definitely "the real deal."

He also says Rousey is the sexiest fighter in the world ... which could be why that armbar doesn't look so bad to him.
