Teen actress Jamie Lynn Spears is staying low key down in the bayou but that hasn’t stopped her from being giddy and showing off her diamond engagement ring from daddy-to-be Casey Aldridge.

Spears, 16, has been flashing the rock to friends and family around Louisiana and Mississippi, a source close to the family tells PEOPLE.

“She’s got an engagement ring,” the source says. “She’s been showing it off, talking about it.”

Congrats to the two youngsters.  No word on a wedding date or any details but I am betting they will have a big wedding at a sugar cane plantation down in Louisiana.
