Britney Spears is prepared to launch legal action against ex-husband Kevin Federline to thwart the former rapper’s plans to feature their children on his new E! reality show.

Reports earlier this week revealed that K-Fed is in discussions to document his day-to-day life with his two sons and his reportedly pregnant new girlfriend, Victoria Prince, as part of a new unscripted reality series. Unfortunately for Kev, his pop star ex is refusing to give permission for Sean Preston, 3, and 2-year-old Jayden James to appear on the show- and is considering launching a legal battle to limit filming, The Sun claims.

In 2005, Britney and Kevin allowed TV cameras into their lives for The UPN reality series Britney & Kevin: Chaotic.
