Britney Spears’ ex-husband Kevin Federline has banned her from getting their two sons involved in her Las Vegas show.

The singer revealed earlier in the week that she would love to get Sean Preston and Jayden James involved in her show during her two year residency at Planet Hollywood in Las Vegas but as it turns out, Federline is not impressed.

“Kevin Federline is c**pping on Britney Spears' bright idea... to put one of their sons on stage during her Las Vegas show, essentially saying, 'Over my dead body’,” TMZ reports.

“Apparently K-Fed was not consulted... and he made it pretty clear to us yesterday he's not keen on the idea.”

Britney seemed set in getting her children involved in the show saying: “Preston will probably be on stage but I think [my other son] Jayden would have a hard time with it”.

Without Kevin’s blessing, Britney will be unable to involve their children as they both have joint custody of them.
