Jamie Lynn Spears, the pregnant 16-year-old sister of Britney, is engaged according to People magazine.
The magazine reports that the teenager has been showing off an engagement ring to friends and is set to marry the father of her baby, boyfriend Casey Aldridge.
Spears, the star of the US children's show 'Zoey 101', sparked a debate late last year after it was announced that she was expecting her first child.
A source close to the teenager told the magazine: "She's got an engagement ring. She's been showing it off, talking about it."
The 16-year-old star became pregnant last year as her troubled sister fought for custody of her own two children with ex-husband Kevin Federline.
