From CBS News' Scott Conroy:

MOUNT VERNON, IOWA -- Mitt Romney is never shy about talking about how much he loves his wife Ann, but today he was a bit more uninhibited than usual.

“She’s a cute girl, I’ll tell ya,” Romney told the Iowa crowd that was packed into a small coffee house here. “She’s hot, too. Wow!”

Romney then appeared to lick his finger and make a sizzle noise, leaving many attendees and members of the media roiling with laughter (and a few others standing silently with their mouths agape).

Governor Romney’s antics came after Mrs. Romney introduced him and handed over the microphone. A man standing next to the governor remarked, “She’s cuter” and then later added, “That’s not saying much.”

Governor Romney had to agree. “That’s exactly right,” he said.
