There’s no one answer to this question since Britney Spears has been married multiple times and her marriages have varied in length and type. However, we can estimate that Britney has been married at least four times.
Her first marriage was to Kevin Federline in 1996 and lasted for just two months. She then married Jason Alexander in 1999 and their marriage lasted for three years. In 2002, she married Jamie James and their marriage lasted for two years before they divorced. Finally, in 2005, she married Kevin Federline again and this time their marriage lasted for six years until their divorce was finalized in 2008.
