Josh Duhamel has officially transformed Fergie into a wife.

The 33-year-old pop star, whose real name is Stacy Ferguson, and the Transformers/Las Vegas hunk, 36, exchanged vows in a celebrity-packed ceremony Saturday in Malibu, E! News has confirmed.

The "Glamorous" singer looked appropriately, well, glamorous in Dolce & Gabbana.

Guests included the bride's fellow Black-Eyed Peas, including will.i.am, as well as Kate Hudson, Mario Lopez, Slash, Kid Rock, Stacy Keibler and brand-new parents Rebecca Romijn and Jerry O'Connell.

Attendees began arriving at the private Church Estate Vineyards near Zuma Beach around 3:30 p.m., shuttled from a parking lot near Malibu's City Hall up to the hillside mansion. The sunset ceremony began about 4 p.m. and lasted about an hour.
