Here's new video of Def Leppard's Phil Collen joining Kiss last night (August 2) in Atlantic City for a roaring in-concert rendition of 'Deuce.'

The clip, courtesy of KissOnLine.com, confirms Collen's superfan status. After all, he's also dressed in Paul Stanley's on-stage costume, following a fun moment earlier on tour when Collen was photographed wearing Gene Simmons' getup.

"He cleans up good!," Stanley says, just before Simmons licks a laughing Collen. He's clearly having the time of his life, as Kiss and Def Leppard continue their first-ever joint tour.

Shows continue through the end of August. Def Leppard then plans to conclude work on their next studio project. This would be the band's first album since 2008′s ‘Songs from the Sparkle Lounge.’
