This has to be the cutest thing we've seen in weeks. Britney Spears' three-year-old niece Maddie tackles Aunt Brit Brit's song 'Up N' Down' from her latest chart topping album 'Femme Fatale.'

Maddie, who is the daughter of Brit's little sister Jamie, is an adorable, tow-headed tot who may just follow in her aunt's footsteps and become a singer, since she's already demonstrating that she can sing and likes to "perform" in this clip. She even gets a round of applause after her rendition. Obviously, that came from the Family Spears, but still. Lil Maddie has performing in her DNA, so it would surprise us even more if she didn't go down the entertainment road.

Brit posted the clip on her Facebook page, writing "OMG! Check out my niece Maddie covering Aunt Britney's Up N Down. Sooooo adorable!" We are not going to disagree. At all.

With her blond doll in hand, Maddie belts out the following lyrics: "The beat just dropped and the room got sexy / You’re watching me like there’s no one else around / I know you want me like kids want candy / So keep watching me go down and up and down."

Now before you go getting all huffy at a child singing suggestive lyrics, have a giggle at the innocence and the cuteness of this little song bit. Besides, who hasn't sung silly pop song lyrics while driving with their kids, nieces or nephews in the car seat, singing along? You know you have. This is no different.
