During a Wednesday appearance on The Ellen DeGeneres Show, Grey’s Anatomy star Ellen Pompeo opened up about family life with husband Chris Ivery and their daughters Stella, 5½, and Sienna, 6 months.

“She liked her at first,” Pompeo said of her elder daughter welcoming the new addition into the family.

But it sounds like Stella changed her mind over time.

“After three months, she was like, ‘Is she leaving?’ ” Pompeo, 45, said. “I was like, ‘No, no, she’s going to live here.’ And she was like, ‘Oh, okay.’ She had about a month where she was not in a good mood. Bad mood every day for a month. And now that passed and now she’s fine.”

All joking aside, Stella “loves” her baby sister — and coming to mommy’s cool place of employment.

“She wants to be an emergency room doctor,” gushed the proud mom. “She loves coming to set. Linda Klein is our medical producer, wonderful woman [and] good friend of mine, and she just wants to go straight to Linda’s office and play with all the medical things.”

She added: “Yesterday I went in to find her [and] she was with Linda with a bone drill, drilling a fake femur bone with a real bone drill. She was supervised, but they have her doing advanced procedures!”

It sounds like the Grey’s Anatomy star is definitely embracing her daughter’s career aspirations.

“She needs to decide whether she wants to be an orthopedic surgeon or an emergency room doctor,” she said. “She needs to nail it down. I mean, seriously, she’s confusing me.”
