Looks like there's another budding pop star in the Spears family.
Britney Spears's niece Maddie Briann, 3, made her You Tube debut Friday with an impromptu performance of her aunt's tune "Up N' Down" – off her latest album, Femme Fatale.
"OMG! Check out my niece Maddie covering Aunt Britney's Up N Down," Spears, 29, wrote. "Sooooo adorable!"
"The beat just dropped and the room got sexy/You're watching me like there's no one else around," sings the tot, who is the daughter of Britney's younger sister Jamie Lynn Spears. "Up and down, up and down, up and down."
