Britney's little sister Jamie, 21, is getting married to her boyfriend of 3 years, Jamie Watson, 30. She broke the news on Twitter, and shortly after posted a pic of her beautiful, round-cut diamond engagement ring to prove it's official.
Spears was previously engaged to Casey Aldrich, the father of her 4-year old daughter, Maddie. But they called it quits in 2010. Sister Britney, 31, unfortunately broke it off with fiance Jason Trawick a few weeks earlier.
