Jamie Lynn Spears, the youngest sister of pop icon Britney Spears, is engaged!

The 21-year-old performer, who is known for her role as Zoey in her long-running Nickelodeon drama show "Zoey 101," is engaged to boyfriend Jamie Watson. She announced the news via Twitter and Instagram.

"Guesssss what??????" Spears Tweeted, with a corresponding photo of the newly engaged couple.

The starlet then Tweeted: ":) #hedidgood," alongside a photo of her engagement ring (See photo below).

The actress has been dating Watson, 30, on and off for around three years, according to People magazine.

The youngest Spears went from Nickelodeon star to teen mom in 2007. When Spears announced her pregnancy, she was starring on the Nickelodeon comedy series, "Zoey 101." The show ended several months later and Spears gave birth to her now 3-year-old daughter Maddie Briann Aldridge in 2008.

Jamie Lynn was engaged to Maddie's father Casey Aldridge at the time. Though the couple reportedly split up in February 2010, they often appear in Twitter photos together.

Jamie Lynn broke the news of her pregnancy in an OK! magazine article and dealt with an onslaught of criticism. She told Glamour that she wanted the news to be in her words and was hurt when tabloids accused her of glamorizing teen pregnancy.

"Obviously seeing [sister Britney Spears' negative tabloid coverage], I knew how far it could go," Spears told Glamour magazine for their March 2012 issue. "I've never wanted to be put under that kind of scrutiny. I just wanted to get away from it as much as I could, to just go away and be a mom and figure out what I wanted, and to earn a sense of respect back for myself. Move to a town in the middle of nowhere and just raise my child. All I could be was a good mother. If anybody had anything to say after that, there was nothing I could do."

The recent news of Jamie Lynn's engagement comes only months after Britney ended her year long engagement to fiance Jason Trawick.

"Jason and I have decided to call off our engagement," Spears said in a joint statement with Trawick in January. "I'll always adore him and we will remain great friends."
