Los Angeles: 'Grey's Anatomy' star Ellen Pompeo is a mother again after welcoming a daughter via surrogate.
The 44-year-old actress surprised fans by announcing she and music producer husband Chris Ivery were parents again after adding little Sienna May to their family, reportedly.
Pompeo took to Twitter and posted a photo of her husband gently kissing their newborn, along with the caption, "Sienna May Ivery welcome to the world. We love you more than words can say."
She also shared her gratitude for her TV cast-mates for keeping the secret of their baby under wraps, adding, "Sienna was born via surrogate & I would like to thank my whole @ShondalandTV family for helping us enjoy these first few weeks privately. Love you (sic)."
Sienna May joins older sister Stella Luna, who was a natural birth in 2009.
Pompeo and Ivery wed in 2007.
