Former Grey's Anatomy star and current Private Practice leading lady Kate Walsh and her fiancee, Alex Young, were among celebrities attending the Chrysalis Butterfly Ball charity event.

The event was co-chaired by a lovely actress, Rebecca Gayheart - the wife of Kate Walsh's one-time Grey's Anatomy love, Eric Dane.

Chrysalis is dedicated to helping disadvantaged and homeless individuals become self-sufficient through new employment opportunities.

Good to see Kate Walsh and her fellow stars supporting a good cause, as well as having a good time with friends.

Here's a picture of Kate Walsh and Alex, along with another shot of them with Grey's Anatomy star Justin Chambers and his wife, Keisha.
