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

Details on the engagement weren’t immediately available. Moore, 24, and Adams, 34, had dated off-and-on since March 2008.

Moore, who supported close pal and ex-boyfriend DJ AM in the wake of his plane crash, has also been linked to musician Greg Laswell, tennis star Andy Roddick, and actors Zach Braff and Wilmer Valderrama.

Adams, a singer, songwriter, producer and author, is best known for his song “New York, New York.” Moore’s next album, Amanda Leigh – a follow-up to 2007’s Wild Hope – will be released May 26.
