Willow Smith's pre-pre-hype machine is in full effect.

Last night (Dec. 5), BET.com posted a trailer for Smith's 'Fireball' video, which premieres tomorrow night on '106 & Park.' The clip -- featuring Nicki Minaj dressed in rainbow-colored boots and a pink wig, who also guests on the track -- is itself a preview for the 10-year-old rhymer's debut album, due out next year on Roc Nation.

The 30-second trailer shows Willow getting down on a city street alongside a crew of dancers and a very colorfully dressed Nicki. The daughter of Will and Jada Pinkett Smith also dons futuristic garb and climbs in front of a green screen for what figures to be some special-effects scenes.

Minaj evidently had a good time on set, and after the shoot, she tweeted a picture of herself posing with the entire Smith crew.

"I'm the newest member of the family! Lmaoooooo," Nicki tweeted. "How cute are they barbz???? Willow goin ham in the video. http://lockerz.com/s/153728773."
