Britney Spears is married ... again.

The pop star and fiance Kevin Federline married Saturday in a private ceremony at a Studio City, California, home, according to wire reports.

Spears and dancer Federline reportedly surprised their families and 20 to 30 guests with the nuptials. The bride wore a white strapless dress and the groom sported a traditional tuxedo in the nondenominational ceremony.

Spears and Federline announced their engagement in June (see [article id="1486880"]"It's True: Britney's Engaged"[/article]) and gave a preview of the wedding in her new video (see [article id="1490551"]"Britney To Marry Kevin Federline In 'My Prerogative' Video"[/article]).

For the singer, this is her second wedding this year. She married high school sweetheart Jason Alexander in a spur-of-the-moment ceremony in Las Vegas in January, but it was annulled 55 hours later (see [article id="1484231"]"Inside Britney's Wild Weekend"[/article]).

Saturday's marriage makes Spears a stepmother, as Federline has two children with actress Shar Jackson.
