Jamie Lynn Spears, the superfluously-named younger sister of Britney, refuses to be a teen mom to a bastard and intends to marry her 18-year-old baby-daddy 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.”

We’ve never been a pregnant teen because Juno hadn’t yet come along to show us just how edgy and irreverent it could be, but sometimes we too show rocks to people and talk about them. Or to them.
