Designer Nate Berkus and The Rachel Zoe Project alum Jeremiah Brent married Saturday in New York City.

According to, the handsome couple exchanged vows at the New York Public Library, marking the first time a gay couple has married at the iconic venue.

Berkus, 42, and Brent, 29, got engaged a year ago during a trip to Peru, where Berkus asked the question atop the 15th-century Inca site Machu Picchu.

Celebrities among the 220 guests included Oprah Winfrey, Rachael Ray, Katie Lee, Rebecca Minkoff, Irene Neuwirth, Busy Philipps and Elizabeth Hendrickson.

Berkus became the first openly gay man to host a nationally syndicated show with the premiere of The Nate Berkus Show in 2010. The syndicated show was canceled after two seasons. Berkus is the host of NBC's reality show American Dream Builders.

Berkus lost former boyfriend Fernando Bengoechea in 2004 while the couple vacationed in Sri Lanka. Bengoechea, a photographer, is presumed dead from a tsunami that hit the island country.
