Willow Smith
On October 6, 2011, "Fireball", a collaboration between Smith and rapper Nicki Minaj, was released. It was released on iTunes two days later and was released to U.S. urban radio on October 18, 2011. In the song, Minaj says: "Ok, I'm the street fighter, call me Chun-Li" making referring to the character Chun-Li from the video game franchise Street Fighter. The song was a commercial failure, failing to chart in any type of music market, except the US R&B chart, charting at 121. It was her first song to miss the Billboard Hot 100. Smith's producer announced that they were almost finished working on her debut album, and that it would be done soon. He also said it has a similar style to "Whip My Hair". The name of the album was later announced to be Knees and Elbows. It was scheduled to be released around April 2012, but was later announced that it would be released later in the year.
