As KISS farewell the army with their End of the Road tour, Simmons and Stanley spoke about whether Frehley and original drummer Peter Criss would be part of the tour.
"Ace and Peter have gotten three chances," he said. "They were in and out of the band — fired — three times. For drugs, alcohol, bad behaviour, being unprofessional … they weren't carrying their load. … So the short answer to your question is we'd love to have Ace and Peter join us here and there. And if they don't, it's not going to be because of us. But they're never going to be in KISS again," Simmons told Guitar World.
He stuck the knife in further saying that he'd invite them on stage for a song or two but Could we depend on either Ace or Peter to do a full set night after night? Not on your f***ing life."
Simmon's scathing response prompted Frehley to fire back with allegations of sexual misconduct towards his wife.
"The icing on the cake was when you groped my wife and propositioned her in Los Angeles at the Capitol Records building behind my back, when I was trying to help you out at one of your "Vault Experiences" which I only found out about several weeks later … she was planning on pursuing a suit against you, but I told her to call it off!" Frehley wrote on Facebook.
Frehley also corrected Simmons, saying he was not fired three times but claims he quit the band twice because Simmons and Stanley "were control freaks, untrustworthy and too difficult to work with."
He signed off the post with a photo of him pointing at the camera alongside the words "the gloves are off."
