Jenny McCarthy's Already Moved On From Jim Carrey

Newly single actress is spotted making out with a mystery man in Vegas

Jenny McCarthy and Jim Carrey announced their split just weeks ago, but Jenny's wasted no time getting over her former funnyman.

She jetted off to Vegas with her sister and some friends yesterday, where the group enjoyed dinner at N9NE Steakhouse inside the Palms—Jenny got lobster, if you must know.

But it's what she had for dessert that's much more interesting...

"After dinner, Jenny headed to the Playboy Club for some martinis and was seen getting very cozy kissing an unknown guy," a hotel source tells me.

Her rep didn't immediately return our request for comment on the Sin City spit swapping.

No word on who the guy is or what he looks like (yet), but she certainly seems to be adjusting to the single life better than her ex.
