Demi Moore and Ashton Kutcher have never let their 15-year difference come between them. The blond chick he was spotted tongue-bathing was actually more like twenty. Star Magazine says:

An eyewitness saw [Kutcher] kissing and groping a hot young blonde by an out-of-the-way bathroom at Italian restaurant Madeo in L.A.

“Ashton had this gorgeous girl pinned against the wall, and he was totally making out with her,” [said the] witness. “I was shocked to see him sucking face with a girl who obviously wasn’t Demi.”

When Demi learns the truth of about the steamy session — which Ashton’s rep denied — it will be her worst fear come true.

“All along, Demi was told it would never work, that he’s going to cheat,” a friend tells Star. “When she finds out that it happened, she’ll be devastated.”

Ashton can always pretend it was an elaborate setup and that she had just been “punk’d” as part of his TV show. Except “Punk’d” has been off the air for almost three years now. On second thought, he should probably just punch her in the hip. Old people have brittle bones and tend to have a hard time getting up once they’ve fallen down. Perhaps you’ve seen their commercial.

Proving she might be 47, but she’s still young (pictures from her Twitter above) and cool (at a Snoop Dogg concert in Vegas this weekend):
