Tennis player Andy Roddick is officially off the market.

The athlete, 26, wed his longtime girlfriend, Sports Illustrated model Brooklyn Decker, 21, in an intimate ceremony Friday evening, has confirmed.

"It was really simple but beautiful," a source tells Us. "Just close friends and family."

Roddick and Decker exchanged platinum wedding bands by Tiffany & Co. during the ceremony, which included a performance by Elton John. The nuptials were intended to be low-key without "a big Hollywood crowd as [Andy and Brooklyn are] not like that," a source told Us prior to the event.

News of the Friday ceremony was first reported last week by the New York Post, who said Decker celebrated her upcoming wedding with bridesmaids during "a big bachelorette weekend" on April 11 in Chapel Hill, North Carolina.

"They just bounced around and had a great time," added the paper.

The couple met in 2007 when Roddick asked his agent to contact Decker's agent after seeing her in SI. He proposed to Decker in March 2008 but said they weren't in any rush to walk down the aisle.
