We just finished recapping the Grey's Anatomy spoilers we know going into next season thus far when we learned of another great guest star coming to Seattle Grace this fall.

Abigal Breslin, the 10-year-old star of the critically-acclaimed comedy Little Miss Sunshine, will guest star in an episode of Grey's Anatomy entitled "Sometimes a Fantasy" this season. The episode has not yet been given an air date, but it should be interesting to see who this young, rising Hollywood star portrays.

Prior to Little Miss Sunshine, Breslin's other film credits include Signs, Raising Helen, and The Princess Diaries 2 (which was written by the one and only Shonda Rhimes). Breslin joins Diahann Carroll, Chris O'Donnell and Eric Dane as notable guest stars on Grey's Anatomy's highly-anticipated Season 3, which stars Thursday, September 21 at 9 pm (just in case you forgot)!
