Nelly - Hot In Herre

"Hot in Herre" is a popular song and single performed by the hip-hop artist Nelly, and was released in 2002 as the first single on his album Nellyville.

There were two music videos made for the single "Hot in Herre", one which takes place in a dance club and has an alternative to the video and one which takes place in the St. Louis Arch. The alternative video was played in MTV Europe instead of the official one.
The original video features cameo appearances by actor/comedian Cedric the Entertainer and NFL players T.J. Duckett and Julius Peppers. It is quite famous because it features a club full of people sweating and stripping to the music
