Is it going to be a shotgun wedding for Jamie Lynn Spears? People reports Britney's pregnant little sis, 16, has received a diamond ring from hometown beau Casey Aldridge, 18.

A Spears family insider tells the mag that the swelling "Zoey 101" starlet, who is reportedly about six months along, has been excitedly blinding friends and family in Louisiana and Mississippi with the glittery bauble.

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

Since revealing her pregnancy to OK! in a December cover story, Jamie Lynn has been lying low in Kentwood, La., hanging out with friends and earning her GED.

When asked about the marriage issue during the interview, she explained, "Right now, we're just focusing on the baby and having a healthy baby. We're trying just to think about that right now so we haven't really talked about that."

The engagement rumblings come on the heels of a PageSix.com item that claimed the teenage sweethearts were temporarily "on the outs," much to the chagrin of mom Lynne.

Alleged a mole, "Lynne feels the public, especially younger crowds, needs to see that Jamie is working things out with Casey."

According to People, there's "no official word" on their purported nuptial plans.
