Los Angeles, Nov. 17 (AP): Britney Spears and Kevin Federline have filed their marriage licence with the county registrar?s office, an agency spokeswoman said.

The Oops! ... I did it again singer, 22, married Federline during a September 18 ceremony in a studio city home, but didn?t immediately file the licence with the county, raising questions about whether they were legally wed.

Kathy Tacawy, a county registrar?s spokeswoman, confirmed yesterday that the documents were filed in Los Angeles county within the 10-day legal window, but declined to comment further.
