Grey's Anatomy

Katherine Heigl is officially a married woman after marrying Josh Kelley in a black-tie ceremony Sunday at the Stein Eriksen Lodge in Deer Valley, Utah.

The beautiful, 30-minute sunset ceremony, which ended shortly after 5 p.m., took place under a giant white tent in front of more than 100 family members and friends, including Grey's Anatomy co-stars Sandra Oh, Kate Walsh and T.R. Knight.

The heated wedding tent, dramatically lit by blue-and-purple lighting and decorated in large white drapes, was filled with silver chairs covered with white cushions on a white carpet. The couple wed on an altar flanked by brass candleholders.

Afterward, her Grey's Anatomy co-star T.R. Knight, who was to have served as a "bridesman," told a reporter: "It was incredible. It was beautiful."

Despite the pre-wedding jitters the actress was experiencing, Katherine's big day seems to have been perfect. Her sister Meg said: "It was great."

Is a baby next on the agenda for the couple?

"I'm super excited to start a family," Katherine Heigl recently remarked. "I've always wanted a family, a large family. But I say that now!"

They met in 2005 when Heigl appeared in the music video for Josh Kelley's song "Only You." She gushed: "I met a guy I can't imagine living without!"

Josh Kelley popped the question to Katie back on June 19, 2006, presenting the blonde beauty with a 3-carat, pear-shaped diamond flanked by pave diamonds. Half of the platinum band is from her mother, Nancy Heigl's, own engagement ring.

Congratulations to Katherine and Josh!
