We haven't heard from Mandy Moore since she agreed to marry Kellan Lutz.

In a move slated for production later this year, that is. They're not dating or anything. In fact, last year, Mandy Moore married Ryan Adams in real life.

Today, it was announced that the actress-singer-songwriter is making a TV splash, slated to guest star on the two-hour Grey's Anatomy finale May 20.

Details surrounding the super-secret gig are being kept under wraps, at least until Shonda Rhimes drops Grey's Anatomy spoilers to spark interest.

It should be fun to see this cutie on the medical drama. But given the amount of people to die on its season finales, we'd better be prepared to cry.
