The 16-year-old actress, who has announced she is expecting her first child, recently passed her high school equivalency exam, the General Educational Development (GED), and plans to continue with her education.

A source close to Jamie - the younger sister of troubled singer Britney Spears - told People magazine: "She's already got her diploma. She wants to take her college entrance test. She's not wasting any time.

"People don't know her. When she gets something in her head, she'll make it happen. Everybody is so supportive of her, and will back her in whatever she chooses to do."

Jamie - who spent time with her baby's father Casey Aldridge in Louisiana over the weekend - previously revealed she wanted to study at Louisiana State University.

She said: "I haven't thought anything about what I might study. I'll have to look more into that.

"But if I went anywhere, I think it would be fun to go to Louisiana State University."
