Motley Crue and Cee Lo Green got into a live mash-up Tuesday night at the Hollywood Bowl.

Cee Lo got on stage with Crue and they performed a mash-up of "Don't Go Away Mad" and Cee Lo's hit "F*** You."

This was a surprising performance to say the least. Check out the video after the jump.

Nikki Sixx was glad to have Cee Lo join them on stage. Cee Lo says he has always been a fan of Motley Crue. After the show, this is what he tweeted:

"NIKKI thanks so much [for] letting me rock with the Crue!!!! A fan for life bro."

Very cool! Our very own Nikki Sixx and Cee Lo green rocking out on stage together. What is your favorite Motley Crue song?
