(People.com) -- Christina Hendricks married fiance Geoffrey Arend at Il Buco restaurant in New York on Sunday, PEOPLE has confirmed.
The redheaded Hendricks, 34, and actor Arend, 31, were engaged earlier this year after being introduced by her "Mad Men" costar Vincent Kartheiser.
Hendricks plays the voluptuous Joan on the show.
The couple exchanged platinum wedding bands made by Tacori.
"The rings are simple and lovely -- so much like Christina and Geoffrey," says Tacori rep Michelle Chila.
Arend's engraved ring matches her petite platinum ring with two rows of pave-set diamonds.
