"Knockout" is a song by Lil Wayne, released by Young Money Entertainment, Cash Money Records, and Universal Motown Records on February 2, 2010 as the fourth single from his seventh album, Rebirth. It contains a guest appearance from Trinidadian-born rapper and Young Money newcomer Nicki Minaj, who performs the chorus and third verse. It also became her first song to enter the US Billboard Hot 100, where it peaked at number 44. A punk-inspired alternative rock song, it finds Wayne comparing him and his inamorata to "Black Ken" and "Barbie", respectively.

Despite being widely panned by music critics, "Knockout" has received platinum certification by the Recording Industry of America (RIAA).^[1]
