Pop kid Aaron Carter announced last week that he was engaged to Playmate Kari Ann Peniche. Kari announced today that the engagment was over.

Peniche tells PEOPLE she and the House of Carters star made the “mutual decision” on Friday. “He’s really young and just needs to get his act together,” she says. “I don’t know what’s going on right now. We’re friends and maybe we’ll get back together sometime. We haven’t ruled out getting back together.”

Sounds like Aaron did something kinda stupid….well beyond asking some chick to marry him at age of 20.

Carter’s rep confirmed the split, telling PEOPLE, “He decided he had made a mistake. He’s young and got caught up in the moment. He hopes they can be friends.”

I guess anyone of us can get caught up when dating hot Playmates. Don’t worry Aaron, more Playmates will come around. About 3-5 a month on average.

Peniche, 22, was named Miss United States Teen 2003, but was stripped of her title after posing for Playboy.
