Ellen Pompeo's Beach Break

Grey’s Anatomy star Ellen Pompeo, aka Dr. Meredith Grey, takes a Sunday stroll on the beach with one of her pet pooches in Malibu, Calif. She recently babysat co-star Patrick Dempsey‘s twins!

“Over the summer, Pompeo and her fiancé, Christopher Ivery, visited Dempsey and wife Jill in London while he was shooting a film in Scotland. Pompeo helped baby-sit the couple’s twin sons, now 8 months, and says she can easily tell them apart: Sullivan “is a little more serious and a little bigger, maybe an athlete, and Darby looks more like a thinker and a poet. He may be the artist.”

USA Today also gives us a behind-the-scenes look on the Grey’s set.

“Busy, busy: Pompeo, dressed in a gray sweater, starts her day by drinking coffee, writing checks and handing receipts to an assistant, whom she promises to reimburse $20 for gas. She chows down on food all day. Before lunch, she’s dipping doughnuts in another cup of joe. After lunch, she runs off to find a stick of gum to get rid of her burrito breath.”

The season 4 premiere episode “A Change is Gonna Come” of Grey’s Anatomy airs next Thursday, Sept. 27 @ 9PM ET/PT on ABC.
