Grey's Anatomy

Meredith and Derek may try for a McBaby this spring. In real life, Ellen Pompeo and her husband Chris Ivery welcomed theirs, daughter Stella Luna, 15 months ago.

Those 15 months make every day feel like a holiday, says Ellen.

“Every day is like Christmas morning. Every day when I go to her room to get her from her crib, that's just indescribable,” the Grey’s Anatomy star tells People.

The 41-year-old actress opened up about her first child and the joys of parenting at the opening of The Cosmopolitan Las Vegas and Marquee Friday.

“I thought I was happy before, but she just brings so much joy. She’s such a happy girl,” she says of Stella, who has been making great strides lately.

“She’s got the walking thing down, which is terrifying, as the falling thing comes with that of course,” Pompeo shares, adding that talking started too.

“When we left the hotel room just now she said, ‘Bye’ [to her father]. She said it once and it was super exciting. I screamed!” Pompeo revealed. “The door was slamming and I opened the door and said, ‘Did you hear that?!’ She’s adorable.”

Seriously. What's not to love about that?
