Jamie Lynn Spears announced her engagement to Jamie Watson on Instagram.
Jamie showed off her fiance and her ring in a post that said, "Guesssss what??????" Jamie, 21 and Watson, 30, have been dating for three years.
This will be Jamie's first marriage -- she was briefly engaged to Casey Aldridge, the father of her 4-year-old daughter Maddie. They split in 2010.
