Britney Spears' husband Kevin Federline has vowed he will not allow his children to go into showbusiness until they learn proper moral values. The aspiring rapper has two children KORI and KALEB with ex-girlfriend Shar Jackson, and seven-month old son Sean Preston with Spears. He says, "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."
