Ellen Pompeo has revealed the first glimpse of 4-month-old daughter Stella Luna.

"Isn't she a doll?" she says on Wednesday's Ellen DeGeneres Show as a photo of the baby appears on a large screen behind her.

Pompeo, 40, says her husband, record producer Chris Ivery, "loves dressing her up like him. He's like, 'Everybody look - we look-alike!' So he goes out and buys her clothes that look like his clothes."

How is she juggling motherhood with her busy Grey's Anatomy schedule?

"I have an amazing baby nurse," Pompeo says. "I couldn't do it without her."
