Washington, Dec 20 (ANI): Britney Spears' ex hubby Kevin Federline found out about her little sister Jamie-Lynn's pregnancy before the singer.

According to reports, Federline or K-Fed as he is known in the media, found out that the 16-year old was expecting her first child before Britney.

As for who broke the news him to him, well it turns out to be Britney's mom Lynne Spears.

Lynne, who has remained close to K-Fed, disclosed the pregnancy to him because she wanted him to be prepared for when her older daughter found out.

"Kevin knew before Britney that Jamie Lynn is pregnant. In fact, Britney's mum Lynne told Kevin about it on Monday, because Lynne wanted Kevin to be prepared when Britney found out," Contactmusic quoted a source, as telling the New York Post.

Lynne Spears and Britney only recently reconciled after they had a falling out earlier this year over the singer's stint in rehab. (ANI)
