Fergie made sure the paparazzi got an eyeful of her impressive wedding rock as she headed off on honeymoon with new husband Josh Duhamel yesterday.

The couple exchanged vows in an intimate ceremony at Church Estates Vineyards in Malibu on Saturday.

The Black Eyed Peas star wore a fitted Dolce & Gabbana gown, draped in diamonds, and carried a bouquet of white flowers studded with crystals. She was flanked by ten bridesmaids wearing contrasting black gowns.
