Jamie Lynn Spears: Engaged to Jamie Watson!

Jamie Lynn Spears is engaged! To Jamie Watson, her boyfriend of about three years now! Get ready for another Spears weddin' y'all! Ding dang!

The 21-year-old confirmed the surprising news yesterday with an Instagram picture of her and Watson hugging while flashing her ring finger.

The caption: "Guesssss what??????"

This will be the first marriage for Jamie Lynn Spears, who was previously engaged to Casey Aldridge, the father of her four-year-old daughter Maddie.

Jamie Lynn split with Aldridge in 2010.

Britney Spears, meanwhile, recently parted with fiance Jason Trawick and is now dating David Lucado, a totally random but very nice-seeming fella.

Congratulations to Jamie Lynn and Jamie - and follow the jump for a bonus pic of Spears' engagement ring. As she captioned the pic, "He did good."

No word on how he popped the question, but we're happy for the couple. Maybe this time, unlike with Casey, she's in a better place to do it right!
