Britney Spears' little sister Jamie Lynn said goodbye to her teens on Monday.
Her 2-year-old, Maddie Briann, gifted her with a chocolate birthday cake and the pair spent the 20-year-old's big day together.
Jamie tweeted the picture of herself with the cake with the caption "Cake from my baby girl! That's a wrap!"
A few hours earlier the former Zoey 101 star also had Happy Birthday sung to her by her daugher's preschool class, tweeting "just got serenaded by Maddie's preschool class- no present will top that!!!"
Jamie Lynn split up with fiancé and father of her daughter, Casey Aldridge, in early 2010.
