It's official! The Grey's Anatomy spinoff, Private Practice, has earned the trust of ABC and has been picked up for a full season, according to E! Online.

This is just the second new series to get picked up for a full 2007-08 television series. The CW's Gossip Girl was the first.

This week's episode of Private Practice, "In Which Addison Has a Very Casual Get Together," averaged approximately 12 million viewers, down from its premiere, but solidifying it as a bona fide success after just four episodes.

We hear that David Sutcliffe was also recently cast as a possible new love interest for Dr. Addison Montgomery (Kate Walsh). Very interesting!

Congrats to Kate, the whole Private Practice cast and its writing team. We're looking forward to a full season - and hopefully many more.
