After leaving their wedding party after 2 a.m. Sunday, Fergie and her new husband — the freshly minted Mr. and Mrs. Josh Duhamel — left that same afternoon for a tropical honeymoon, reports.

The singer, 33, and the actor, 36, had tied the knot at the Church Estates Vineyards in Malibu.

When the newlyweds arrived at Los Angeles International airport around 2 p.m., Fergie showed off multiple plain and diamond studded wedding bands.

“They pulled up in a limo SUV, and Fergie got out first and smiled. She looked so happy. After Josh got out with a carry-on bag, he immediately grabbed Fergie’s hand in a very loving and protective way,” one eyewitness tells People.

“Fergie said that the wedding was amazing before Josh chimed in and added that the wedding was great.”

Asked if she will have any kids soon, Fergie said jokingly, “I’m pregnant with twins,” the magazine adds.
