It's a girl.
Grey's Anatomy and Private Practice star Caterina Scorsone (Amelia) welcomed daughter Eliza to the world on July 6, 2012 at home. This is her first child with her husband Rob Giles.
On July 8 Caterina tweeted, "Thanks so much for all of the wishes and blessings! Eliza, Rob and I are doing great and are deliriously happy and a bit sleepy."
