Mandy Moore: Engaged to Ryan Adams!

Mandy Moore will tie the knot with musician beau Ryan Adams, her publicist confirms.

Details on the engagement weren't immediately available. Moore, 24, and Adams, 34, have dated off-and-on since March, although there was a brief break in there.

Moore supported friend and ex-boyfriend DJ AM in the wake of his surviving a plane crash, and was even rumored to have gotten back together with AM briefly.

She has also been linked to singer Greg Laswell, tennis star Andy Roddick, and actors Zach Braff and Wilmer Valderrama in the past. But Ryan Adams won out!

Adams, a popular singer, songwriter, producer and author, is perhaps best known for his song "New York, New York." Mandy Moore's next album, Amanda Leigh - a follow-up to 2007's Wild Hope - will be released May 26.
