LeAnn Rimes and Eddie Cibrian Are Married!

It's official: Eddie Cibrian and LeAnn Rimes are husband and wife!

"LeAnn and Eddie were happily married today surrounded by their closest family and friends," the bride's spokesman, Rhett Usry, confirms exclusively to PEOPLE. "They thank everyone for their well wishes."

Country star Rimes, 28, wore a Reem Acra gown as she and actor Cibrian, 37, exchanged personalized vows on Friday in front of about than 40 guests, including Cibrian's sons Mason, 7, and Jake, 4, from his previous marriage.

The couple had led friends and family to believe that they'd been invited to an engagement party, but surprised the guests by tying the knot at the intimate ceremony held at a private home in California.

"I'm looking forward to settling down," Rimes recently told PEOPLE of her impending nuptials. "Settling into our life."

The couple got engaged in December when Cibrian proposed with a 5-carat diamond ring from jeweler Brent Polacheck, who also crafted their wedding bands.
