Ever wanted to hear a mashup of Motley Crue And Cee Lo? Well you’re in luck, but unlike some of our other favorite metal related mashups, this one was done by the actual artists themselves.

Motley Crue were joined onstage by the R&B singer/The Voice judge during their show at The Hollywood Bowl this past week. Before Vince Neil started singing the lyrics to “Don’t Go Away Mad,”  Mr. Green began singing his big hit “Fuck You.” You can watch the mash up performance, where Cee-lo also sang along with Neil during the outro, up top.

Nikki Sixx also posted a picture of himself with Cee-lo backstage via Twitter. Later in the night , Sixx tweeted “No thank you..Let write some damn music. now….:)” in response to Cee-lo’s tweet. Motley Crue recording music with Cee-lo? And we thought Metallica and Lou Reed was an odd combo.
