Sometimes, I’m not quite sure what to think of Ashton Kutcher. There are days when he seems like a major-league a-hole, and yet there are other days when he seems like a really decent guy. I’m not sure where this story falls, but I will give Ashton credit for stepping up and being chivalrous, even if he made a scene. Here was the situation: Ashton and Demi (and their “date” Jennifer Aniston) all participated in the “24 Hour Plays” on Broadway Monday night. The event was a success, and Demi, Ashton and Jennifer were all enjoying the afterparty. Until a dude started talking smack about Demi, apparently making some rude remarks about her being a cougar (or “puma”). Ashton got in the guy’s face and “a massive verbal fight then ensued”. Here’s more:

Ashton Kutcher was all smiles in NYC on Monday night following his successful Broadway debut in which he made the audience roar with laughter while playing the boyfriend of a hilariously neurotic Eva Mendes in Montblanc’s 9th Annual “24 Hour Plays.”

However that smile was wiped away about half-an-hour into the after-party at Crest Lounge’s Opera Ballroom.

According to an eyewitness, Kutcher’s co-star and wife Demi Moore was mocked by another party guest, sending her 31-year-old husband into an angry rage.

“Demi and Jennifer Aniston were happily sitting together in the VIP when this guy starting really obviously making fun of Demi and things like her relationship with a younger man,” an insider said. “It went on for quite a while. Ashton heard it and approached him. At first he thought the guy wasn’t serious and was like ‘what the?’ He then realized he was serious. Ashton lost it.”

We’re told a massive verbal fight then ensued between Ashton and the guest, as Demi, 47, looked very embarrassed over the whole situation.

“It got pretty heated, nobody knew what to do,” added the source.

The Hollywood duo stormed out via the back entrance along with friend Jen Aniston. Reps for Kutcher and Moore did not respond for comment.

Well… at least it didn’t get physical? That’s the best I’ve got. If it’s just two dudes screaming at each other, it’s not some huge deal. This guy who was making fun of Demi sounds like a douche, and he probably didn’t figure Ashton would have the stones to stand up to him. That being said, whenever I’m at a bar or a party and I see two guys screaming at each other, I always get embarrassed for them. I always think, “Drunken a-holes, much?” Maybe it would have been classier to have words with the guy and just walk away the bigger man. But I’m not judging! I’m sure Demi got turned on seeing Ashton defend her honor.
