They start off young.

Britney Spears started performing in public at age 5, and now her niece, Maddie, may be on the same path. Maddie, 3, is daughter of Jamie Lynn, 20, Spears' younger sis. Over the weekend Britney Tweeted a vid of Maddie singing the song "Up N' Down" off of Brit's latest album, Femme Fatale. Said Brit:

    "OMG! Check out my niece Maddie covering Aunt Britney's Up N Down. Sooooo adorable!"


Sings Maddie, "The beat just dropped and the room got sexy/You're watching me -- there's no one else around ... Up and down, up and down, up and down."

What do you think -- is this vid cute, or is Maddie too young to be singing that tune?
