Britney Spears' sister Jamie Lynn Spears is pregnant at the age of just 16.
Jamie Lynn revealed she is "shocked" to be expecting her first child with boyfriend Casey Aldridge.
She said: "It was a shock for both of us, so unexpected. I was in complete and total shock and so was he."
The 'Zoey 101' star, who is 12 weeks pregnant, kept the news a secret until she got used to the idea. She told her mother Lynne shortly before Thanksgiving.

She told America's OK! magazine: "I took two weeks to myself where I didn't tell anybody.
"Only one of my friends knew because I needed to work out what I would do for myself before I let anyone's opinion affect my decision. Then I told my parents and my friends. I was scared, but I had to do what was right for me.
"My mom was very upset because it wasn't what she expected at all. A week after she had time to cope with it and became very supportive."
Jamie and Casey, who have known each other for years, began dating in high school.
Although Jamie is pleased about the pregnancy, she has advised her young fans to abstain from sex until they are married.
She said: "I definitely don't think it's something you should do, it's better to wait. But I can't be judgmental because it's a position I put myself in."
