Looks like a happy ending for everyone. At least this week. Just over a month after his ex-girlfriend Mandy “Suckfest” Moore got hitched to Ryan Adams, Andy Roddick tied the knot with his girlfriend, model Brooklyn Decker.

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

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.

So let’s get this straight: They met because he liked some photos of her in a bikini. He had his people talk to her people. She’s 21. And now they’re married. This is gonna last a looooong time, people. Like maybe even six months.

Mandy Moore, I’m looking at you.

Andy Roddick got engaged to model Brooklyn Decker.

Andy’s 25 and Brooklyn is 20.

Yeah, this is gonna work out.
