Peet, 34, who stars in the NBC drama Studio 60 on the Sunset Strip, wed screenwriter David Benioff, 36, on Saturday at Peet's alma mater, Friends Seminary, a Quaker school in N.Y. City.
Guests included Elizabeth Berkley and Mark Ruffalo. Nick Carter? Not there. Come on, that would be absurd.
"[The ceremony] was amazing and as extraordinary as she is," said Berkley, reports People.
The bride walked down the aisle wearing a strapless white dress with a black sash, carrying a bouquet of roses. Following the ceremony, guests made their way to the Chelsea Art Museum for the reception.
The wedding went smoothly despite the fears she revealed on The Late Show with David Letterman.
"I have been having recurring nightmares about, not the ceremony, but the party. I go to the bathroom and I come back to the party and everyone's gone. Except for some, everyone's dispersed. And another one where the band just didn't show up so everyone got bored. And I was begging musicians that I know to just play, 'Play something!'" confessed Peet.
The wedding came two weeks after Peet announced that there was a bun in the oven. The couple dated for four years after they were set up on a blind date through friends. They became engaged in July of 2005. This is the first marriage for both. Yay.
