Britney Spears isn't giving up her sons, Sean Preston and Jayden, without a fight. The singer has employed a private detective agency to dig up evidence that her ex-husband Kevin Federline is not a model parent.
According to insiders, representatives of Lisa Javoric Private Investigators followed Kevin on his August 17 trip to Las Vegas. "Britney has an arsenal of dirt on Kevin," a friend of the singer explains. "She is not going to just hand over their sons and more money to Kevin. She is going to fight him tooth and nail."
