Soul singer Cee Lo Green hopped onstage in the middle of Motley Crue's set at the Hollywood Bowl in Los Angeles last night. However, Green did not lend his voice to 'Girls, Girls, Girls' or 'Shout at the Devil'; rather, he joined Vince Neil, Tommy Lee and the rest of the Crue to sing his hit 'Forget You,' [a.k.a. 'F--- You'] as part of a mash-up with Motley's 'Don't Go Away.' Check out an audience-recorded video of the jam below.

Bassist Nikki Sixx posted a photo of himself and Green on Twitter after the show, writing "Mr. Cee Lo Green came onstage with us tonight at The Hollywood Bowl for a mash-up of 'Don't Go Away-Forget You.'"

Green echoed the sentiment on his own Twitter, writing "NIKKI thanks so much [for] letting me rock with the Crue!!!! A fan for life bro."

Noisecreep wants to know when the on-record collab is scheduled!
