Jamie Lynn Spears' little three-year-old girl is making a big splash on YouTube with her debut performance of auntie Britney's latest single "Up N' Down."

The video, which is rapidly approaching one million views, was tweeted by Britney who called it "Sooooo adorable!"

The song "Up N' Down" is off of Britney Spear's new album Femme Fatale. In the video, Maddie clutches her Barbie doll and mixes up a few of the lyrics, singing, "I know that kids want candy" instead of "I know you want me like kids want candy."

Jamie Lynn, 20, who announced her pregnancy while starring on the Nickelodeon comedy, "Zoey 101," ended the show and gave birth to Maddie in 2008. She was engaged to Maddie's father Casey Aldridge at the time, though the couple split in February 2010.
