More rumours have emerged today suggesting that Britney Spears is planning to divorce Kevin Federline.

The singer is apparently furious about her husband's partying lifestyle and does not believe that they can sort through their differences.

"She's planning to divorce him on the grounds of adultery," a source told the News of the World. "Kev has just carried on his partying ways and been spotted with various women."

The report also claims that Federline has angered Spears by leaking stories about her to the US media.
