K-Fed knew of pregnancy before Britney

Kevin Federline found out that Jamie Lynn Spears was pregnant before her sister Britney did, according to reports.

Britney's ex-husband was told the news by her mother Lynne who wanted him to know what was happening.

A source told the New York Post: "Kevin knew before Britney that Jamie Lynn was pregnant. In fact, Britney's mum Lynn told Kevin about it on Monday because Lynne wanted Kevin to be prepared."

Earlier today Britney reportedly told a news agency: "My sister is not pregnant!" But she later released a statement confirming that she was aware of the news after it was made public, saying: "Britney is aware of...Jamie Lynn's pregnancy. She wishes her sister nothing but the best and asks for privacy during this time."
