Spears has been married three times - her first being a 55-hour "spur-of-the-moment" marriage to childhood friend Jason Alexander in January 2004. The pair wed in Las Vegas, but a then 22-year-old Spears annulled the nuptials two days later, reportedly on the advice of her management team. In September 2004, she married the rapper and dancer Kevin Federline in Los Angeles, after a two-month engagement. The couple - who share sons Sean and Jayden together - split in 2006, with Spears citing "irreconcilable differences" in her divorce papers.
