fergieFergie married boyfriend Josh Duhamel in a white-themed ceremony in Los Angeles yesterday.

The couple of four years got engaged in 2007 but only announced their plan to marry last month and kept the location of the nuptials - the Church Estates Vineyards in Malibu - secret even from guests until yesterday. The ceremony took place under magnolia trees in a spot decorated with thousands of white roses.

The bridal party were all dressed by Dolce & Gabbana: Fergie wore a white, corseted wedding gown with a tulle overlay and spaghetti straps which she accessorised with an estimated $1million of diamonds by H. Stern. Transformers star Josh and his groomsmen wore black suits with white ties, while Fergie’s ten bridesmaids wore black gowns.

Fergie carried a bouquet of white flowers studded with crystals and the couple exhanged H. Stern diamond rings, engraved with special personal messages by the bride and groom.

Guests included Kate Hudson, Kid Rock, Mario Lopez, Fergie’s Black Eyed Peas bandmate will.i.am, new parents Rebecca Romijn & Jerry O’Connell, and Josh’s Las Vegas co-stars James Caan, Molly Sims and Vanessa Marcil.

One wedding guest described the ceremony was “beautiful” and that Fergie “looked amazing .. [she] has lost all the weight she gained for Nine.”

The couple started off their wedding week with a joint hen and stag party on Wednesday night in Santa Monica, followed by a Hawaiian-themed rehearsal dinner on Friday night.
