Guess "The Rumors Are True", folks, Jamie Lynn Spears is engaged to baby daddy Casey Aldridge, and X17 has the proof!

While out registering for her unborn child at Babies R Us in Louisiana yesterday, Jamie Lynn showed off not only her growing belly, but her diamond engagement ring as well!

And just what kinds of items are on Jamie Lynn and Casey's registry?

Although the black Bugaboo Stroller and white Ultrasound Picture Frame seem pretty gender neutral, Jamie does want her child to have a John Deere First Keys teething ring. Is she due (on July 10th, apparently) to give birth to a boy, like Brit?

She's also registered for a Learn & Groove Musical Table! Sounds like she wants to keep music in the family - maybe Auntie Britney will buy that for her!
