The Black Eyed Peas singer, 33, wearing a Dolce & Gabbana gown, and the actor, 36, tied the knot at the Church Estates Vineyards in Malibu.
Fergie carried a bouquet of white flowers studded with crystals as the couple exchanged H. Stern rings engraved with personal messages. Ten bridesmaids were dressed in contrasting black.
Fergie’s specially-designed engagement ring featured a 4-carat brilliant cut diamond set amid other diamonds. A narrowed diamond wedding band completed the set. Duhamel’s ring was made of white gold with a brushed finish.
The ceremony was followed by a reception in a tent decorated as a forest of trees, with the ceiling covered in lights.
Among the invited guests were new parents Rebecca Romijn and Jerry O’Connell, Mario Lopez, Stacy Keibler, Kid Rock, Slash, Kate Hudson (Fergie’s costar in her upcoming movie Nine), the members of Black Eyed Peas including will.i.am, and Duhamel’s Las Vegas costars James Caan, Molly Sims and Vanessa Marcil.
Also expected were Duhamel’s family, who flew in from his home state North Dakota. “His family are so excited,” says a friend of the couple. “They really love Fergie and are so happy to welcome her to the family.”
Fergie, aka Stacey Ferguson, who has been working out to prepare for her wedding, “has lost all the weight,” says a source. “She looked amazing.”
The wedding week kicked off Wednesday night with a joint bachelor-bachelorette party at the newly opened Dakota Lounge in Santa Monica, followed by a Hawaiian-themed rehearsal dinner on Friday.
“Josh is a great guy,” says Mario Lopez, who shared his first kiss with Fergie as kids and later became close friends with the singer. “They will be great together.”
