Patrick Dempsey Debuts His Twins!

Patrick Dempsey is one proud papa as he cuddles new twin sons Sullivan Patrick and Darby Galen. Born Feb. 1 at an L.A.-area hospital, the boys made their debut with some help from dad, whose role as Dr. Derek "McDreamy" Shepherd on Grey's Anatomy came in handy. "I was watching everything that was going on (with the doctors), and you see a lot of that in the show," says Dempsey, who helped cut the cords – both of them!

With the little ones fast asleep, Dempsey, makeup artist wife Jillian and their daughter Talula, 5, share a happy moment at home in Los Angeles. The new dad admits that when the couple first learned they were expecting not one, but two new additions, "I was a little overwhelmed." But looking ahead, the racing enthusiast is already revved up to take the boys out for their first spin. Racing "is such a family sport," he says.

"There have been a lot of great gifts," says Dempsey of the influx of baby presents – including these mini scrubs (inscribed "McCutie" and "McCudlie" in homage to Dempsey's Dr. McDreamy character) from Ellen DeGeneres. But perhaps McGrumpy and McThoughtful are better suited? Dempsey says of the fraternal twins: "Sullivan will probably read this article in 20 years and say, 'What did you say about me?' He's sort of the grumpy old man. Darby is very much the peaceful, quiet little Buddha."

With three little ones in the house, Dempsey says, "I think we're done now." As for how daughter Talula is handling big sister duties? Dempsey says not only did his 5-year-old help determine the boys' names, she's "very excited and very good about taking care of her brothers."

Since the boys' arrival, Dempsey, who acknowledges the newborn phase isn't his specialty ("Certainly for the first four or five months, the husband is really kind of a houseboy"), has enjoyed an even closer bond with his little girl. The two bicycle together and watch movies like The Sound of Music, while the boys are settling into a familiar routine with mom: Wake up, cry, eat, poop and sleep.

Dempsey, who met wife Jillian in 1994 when he turned up at her L.A. salon for a haircut, gifted her with diamond studs after the birth of their sons. "She's never been more beautiful to me than she is now," Dempsey (here at last year's Emmy Awards) says of his wife during her pregnancy.
