Britney Spears reportedly didn't know that her 16-year-old sister was pregnant. She basically found out the same way we did.
A family friend told People, "This is going to kill her...In the end, she'll be supportive, but this is a big shock."
Apparently, the two sisters don't have any beef with each other but Jamie Lynn's people have told her to keep her distance from her older sister.
"Britney doesn't have to listen to anyone now but her sister still does so who knows what people are telling her," says the source. "She has her career now too."
All I can say is that Jamie Lynn is making her big sister Britney look good. Who knew that could ever happen?
