It looks like Jamie Lynn Spears, 21, and her boyfriend Jamie Watson, 30, will be sharing more than their first names, now that they’re engaged. She announced the news Sunday via Twitter with a photo of herself flaunting the beautiful diamond, while posing with her soon-to-be husband. The young mother rose to fame as Zoey Brooks in Nickelodeon’s Zoey 101, before taking a hiatus from acting after becoming pregnant with now four-year-old daughter Maddie. The couple have been together for three years, following her failed engagement to Maddie’s father, Casey Aldridge. Britney, who recently called off her one-year engagement with manager-boyfriend Jason Trawick, couldn’t be happier for her younger sister. The pop star took to Twitter to express her happiness, writing: “So excited and happy for my sister, congrats @jamielynnspears – love you.” ~Brittnee Fleming
