I give it 6 months. Tops.

Mandy Moore and Ryan Adams have gotten engaged, People.com reports. OK. What?! This is doomed to fail. She's dated everyone from Wilmer Valderrama to Andy Roddick to DJ AM (read: has bad taste). And he's a wackadoo rock star who may have cleaned up his image, but is not the kind of guy you want to marry. I love his music, but I've seen interviews with him and he's bonkers.

I'm going to take bets as to when this relationship ends, have your say in the comments section. My prediction: 6 months - engagement called off.
