Happy Birthday To You, Jamie Lynn Spears!

Given the amount of attention she’s been receiving as of late, we’re surprised no one has wondered what her sister’s been up to sooner!

While Britney Spears is busy promoting her brand new album, Femme Fatale, her lil’ sister, Jamie Lynn Spears, turned 20 years old over the weekend, and took to her relatively new Twitter account to share some pics from the big day of her with her adorable baby, Maddie Briann!

Check out the photo (above), which was captioned:

What else do you do on your 20th birthday weekend?

Look how big Maddie’s gotten! And she looks so happy!

Mom must be doing a great job!

Hope you guys had a nice little day together!
