Jenny McCarthy already has a new man! Jim who!?! McCarthy hit Hollywood with her new mystery man after splitting with long-term partner of 5 years Jim Carrey a month ago. The hot new couple dined at Katsuya before heading to the Roosevelt hotel and Crown Bar. They couple finished up going to a hotel in Santa Monica.

more Jenny and her mystery guy after the jump…

McCarthy, 37 certainly hasn’t wasted any time finding a new man, not sure if she picked him up at the valet (just kidding). She was spotted out on her second date this month with this new mystery man.

“It definitely wasn’t a first date, but you can tell it’s a new relationship. Jenny and her man were very affectionate with each other, and didn’t stop holding hands throughout dinner,” an eyewitness at Hollywood hotspot Katsuya tells HollywoodLife.com of the May 14 date. “They stayed for 2 ½ hours!”

The snitch adds, “Jenny’s new boyfriend mentioned that he was on a no-carb diet and sent back the sushi for sashimi!”

No carbs at all, ha! That’s exactly what I should be doing.

Do you think Jenny and this new dude will stick around for a while or he’s just for the show? No matter what he sure seems to be helping Jenny to move on. Well done woman!
