Jamie Lynn Spears Engaged?

According to People magazine, Britney Spears's little sister, Jamie Lynn, is engaged.

Apparently, the pregnant 16-year-old has been showing off her ring, given by boyfriend and father-to-be Casey Aldridge, claiming that it is an engagement ring.

A source told the magazine, "She's got an engagement ring. She's been showing it off, talking about it."

In an interview, Aldridge's grandfather told Daily News that he would be happy to see the young couple tie the knot, "Yes. But whatever happens, happens." However, the 70-year-old admitted that he has not yet heard of any engagement, "I don't know a thing about it."

Jamie Lynn and Casey Aldridge are expecting their baby this summer, but have not yet officially confirmed their engagement or wedding plans.
