(Yahoo!) - Jamie Lynn Spears is off the market.

Britney’s little sister, 21, who, just like her sister has had a rocky  relationship history, finally found a man to put a ring on it. She announced her  engagement to the same-named Jamie Watson last night on Instagram.

“Guesssss what??????” she wrote on her Instagram page.

She followed  it up right away with a close-up shot of her engagement ring. “☺ #hedidgood” she wrote.

And the ring is certainly nothing to scoff at. The diamond studded piece  features a huge rock in the center, surrounded with what appears to be more  smaller diamonds around the band.

So, just who is the lucky guy? Watson, 30, is Spears’ boyfriend of three  years. Not too much is out there about him, besides that he’s a businessman and  not involved in the entertainment industry.

Watson spoke with The New York Post's Page Six in January  about the state of their relationship. He told the paper that their  relationship, “is really going great.” He explained that while they’ve broken up  before, “We’ve been back together for a while now.”

And they seem very much in love from the many pictures of them together littered throughout  her Instagram – this is clearly a couple that has deep affection for each  other.
