Willow Smith 'Living Life' On Rebellious '21st Century Girl'

Tween star's second single premieres on 'On-Air With Ryan Seacrest.'

After temporarily taking over the globe (and probably inducing some permanent neck problems) with her chart-smashing "Whip My Hair," pint-size prodigy [artist id="3797575"]Willow Smith[/artist] is back in action with her new electro-pop banger "21st Century Girl."

The 10-year-old superstar premiered the track on Monday morning (February 28) on Ryan Seacrest's radio show, where it was announced that the song will be available exclusively on iTunes starting Tuesday.

The song is as current as they come — she sounds like a fusion of Ke$ha and Rihanna. Willow celebrates being a girl of the moment, all the while backed by a hyper-dancey beat. "The rules don't own me/ I'm living life on the edge," the singer coos.

Smith will also be performing the track, produced by Twin and Alke, on Tuesday's episode of "The Oprah Winfrey Show." All this news comes on the heels of Smith's newly announced addition to 13 U.K. dates on Justin Bieber's journey across the pond with his super-successful My World Tour.

The young talent may be relatively new to the music scene (and the world in general), but her work ethic is inarguably beyond her years.

"It felt like all the hard work paid off, mostly that," Willow told MTV News last October about the success of her first single. "Like all the hard work that I've done, like recording 'Whip My Hair' — it's paid off."

Willow has also recently hinted at an upcoming album, tweeting, "Are you excited for my album!? It's coming soon..... VERY soon!!" Although there's no official release date for the LP, a video for Smith's new single is said to be coming out shortly.
