Britney's little sister posted two pictures to Instagram on March 3rd, the first of which depicted Jamie Lynn with her longtime boyfriend and new fiancee, Nashville businessman Jamie Watson. Jamie Lynn accompanied the post with a tweet showing her excitement.
Jamie Lynn later followed up a close-up of the round-cut sparkler, using the hashtag "#hedidgood". It looks like Watson certainly did do good, as evidenced by the adorable snap of the happy couple. We can't wait to see what's in store for the pair!
