Patrick Dempsey, who plays Dereck (Dr.McDreamy) Shepherd, on Grey’s Anatomy and his wife Jillian are the proud parents of baby twin boys. The twins were born on Thursday in Los Angeles.

The twins, named Darby Galen and Sullivan Patrick, were born in Los Angeles. They join 4-year-old sister Talula in the Dempsey household.

Asked how fatherhood has changed him, he told the magazine, “Now, making money is about providing for my children. And being a father makes you look at yourself. You look at your marriage and go, ‘How do I improve this? How do I keep growing and create a stable environment for my children?’ “

Congrats to Patrick and Jilian!
