More than 75 family and friends attended the ceremony at Shep and Renee Gordon's home, including actor Dax Shepard, who served as Arnold's best man. Andrea Groussman was the maid of honor and designed the couple's rings.
Arnold and home organizer Groussman, who wore a Claire Pettibone gown, met through mutual friends in April 2008. "I knew that if I could get Ashley to fall in love with me, I'd never have to worry about anything else as long as I lived," Arnold wrote on the couple's weddingchannel.com page. The two became engaged this past March at Arnold's 50th birthday party. "I'm the luckiest girl in the world!" Groussman wrote.
