Guess someone from the Spears family is getting married after all!

Over the weekend, Jamie Lynn Spears, Britney's little sister, got engaged to boyfriend of three years Jamie Watson and happily took to Twitter to reveal the exciting news!

"Guesssss what??????" the 21-year-old singer posted, followed by a picture of her hugging her 30-year-old fiance with a huge rock on her hand.

Virtually minutes later she one upped her tweet with an Instagram close up of her engagement ring.

That's one huge rock!
