It looks like Jamie and Lynn Spears will be throwing a wedding after all, but not for Britney! Her little sis Jamie Lynn Spears is engaged to her boyfriend of three years, Jamie Watson. She shared the exciting news on Twitter writing, "Guess what!?" and moments later shared a close up of the round diamond adding, "He did good!" Jamie was previously engaged to Casey Aldridge the father of her four year old daughter, Maddie. Oh well, if Britney couldn't be the bride this year at least she'll be the maid of honor! Congrats to the happy Jamies!
