Kevin Federline says he will not allow his children to go into showbusiness until they have moral values.

The ex-dancer and wannabe rapper has two children from his relationship with Shar Jackson, and is married to Britney Spears, with whom he has seven-month-old Sean Preston.

He explained: "I'll encourage it, but not until they're adults. I'm not gonna let them be in this business when they're kids. I don't believe in that. It's too hard on them. They need to learn life values first."
