Kevin Zegers, the "Gossip Girl" alum who will next appear in "The Mortal Instruments: City of Bones", is officially off the market. The actor married his longtime girlfriend, talent agent Jaime Feld, Saturday, August 3 in New Jersey.

The couple exchanged wedding vows in front of family and celebrity friends. According to Us Weekly, their famous guests included his "Mortal Instruments" co-star Lily Collins, Julianne Hough and Sophia Bush, whom he credited as their matchmaker.

"I did a movie with Sophia like six years ago and she set me up with Jaime, her best friend," 28-year-old Zegers once revealed to ET Canada.

He proposed to her in April. "I took her out for a walk in the morning with our dog, went down to the beach and proposed," he recalled. "We've been together for six years, so I've been through a lot of stuff with her."

Details of their nuptials are still unclear, but the groom spilled earlier this year that it would be a traditional Jewish wedding. One day before the big day, he enjoyed a relaxing time with his friends as tweeting, "Round of golf with my boys before wedding weekend starts."
