Grey’s Anatomy star Ellen Pompeo and her husband Chris Ivery have welcomed their second child together, a baby girl. The actress made the announcement on Twitter last night. She wrote: “Sienna was born via surrogate & I would like to thank my whole @ShondalandTV family for helping us enjoy these first few weeks privately”. She also shared a sweet snap of the new arrival on Instagram (see below) which she captioned: “Sienna May Ivery welcome to the world. We love you more than words can say”. Ellen and Chris, who tied the knot back in 2007, are already parents to a five-year-old daughter called Stella Luna.
