Jamie Lynn May Be Hearing Wedding Bells

With a bun in the oven, teen star Jamie Lynn Spears now appears to have gotten an engagement ring from boyfriend Casey Aldridge, People reports. "She's been showing it off, talking about it," says a source close to the 16-year-old Spears, who's been hiding out in the Louisiana town where she and sis Britney were raised. No word on a wedding date.

Spears, star of Nickelodeon's Zoey 101, is due this summer, though details of the pregnancy have been few and far between—and there have been rumors that Aldridge, 18, is not, in fact, the father. But the source tells People the rock is from Aldridge, and it's been on display as Spears visited friends and relatives in Louisiana and Mississippi. (More Jamie Lynn Spears stories.)
