Pop star Britney Spears and her husband, Kevin Federline, have filed for divorce, court officials in Los Angeles say. Spears, 24, who married 28-year-old Federline in 2004, will seek custody of their two children, court papers say. The documents cited “irreconcilable differences” for the divorce. Spears’s previous marriage, to childhood friend Jason Alexander, was annulled two days after the couple exchanged vows in Las Vegas in 2004. Spears gave birth to her first child by Federline - Sean Preston - last year. The couple announced the birth of their second child, named as Jayden James Federline in the divorce paper, in September. The documents state the day of separation as 6 November. In the papers, Spears asks that each party pay their own legal fees and does not request spousal support. She also requests assets including “miscellaneous jewellery and other personal effects” and her earnings from after the separation date be confirmed as separate from her husband's property. Spears has sold more than 60 million albums since her pop debut in 1998.
