Dr. McDreamy has doubled his pleasure.
Patrick Dempsey and his wife, Jillian, are the proud parents of twin boys, Darby Galen and Sullivan Patrick, born Thursday in Los Angeles, the actor's rep confirmed to E! News.
The couple also has a five-year-old daughter, Talula Fyfe.
The Dempseys first confirmed they were expecting in September. They later amended their announcement to reflect the impending double delivery.
Though Jillian Dempsey has credited her husband with being a "very hands-on" father, she has also said that brand-new babies aren't exactly his bag.
"He's the first to admit he prefers the more interactive stage of children versus newborns," McDreamy's missus said in January's Life magazine. "The newborn phase is difficult for fathers—they don't feel the connection because babies are all about breast-feeding."
However, the Grey's Anatomy star "of course" does diaper duty, she said.
As for Dempsey, he said that being a father has changed his outlook on life, love and his career.
"Now making money is about providing for my children. And being a father makes you look at yourself," Dempsey told Life. "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?' "
The Dempseys were married in 1999 at his family's home in Maine, after they met at a hair salon in 1994.
It was the second marriage for Dempsey, whose first marriage to his former manager, Rocky Parker, a woman 27 years his senior, ended in divorce in 1994.
With his home life undoubtedly a bit busier as a result of the new arrivals, Dempsey can at least expect things at work to finally start settling down.
After big wins at the Golden Globes and the SAG Awards, the Grey's Anatomy cast has completed their red carpet duties for the awards show season.
Meanwhile, Isaiah Washington was due to return to the Seattle Grace set this week after taking time off to seek counseling in the wake of the gay slur outburst heard round the world.
Series creator and executive producer Shonda Rhimes said in a statement last month that she was hopeful Washington's decision to enter treatment would provide the "foundation for healing" necessary to move beyond the incident.
