Grey's Anatomy star Chyler Leigh is going to be a mom again!

The 26-year-old actress and her actor/musician husband, Nathan West, are expecting their third child, her rep confirmed this afternoon.

"She is a little over four months pregnant," her rep said, adding that "Grey's Anatomy won't be writing her pregnancy into their storyline."

Chyler Leigh and Nathan West are parents to Noah Wilde, 5, and Taelyn, 2.

She just missed the cut for our tribute to the Celebrity Babies of 2008, but we expect Chyler and Nathan's little bundle of joy to lead the 2009 entrants!
