Gene Simmons and Paul Stanley are deeply saddened by the loss of Ace Frehley, their former KISS bandmate.

“The news of Ace Frehley’s passing leaves us heartbroken. He played an integral and irreplaceable role as a rock icon during KISS’s pivotal early years,” they expressed to Page Six in a statement on Thursday.

They continued, “Ace remains an enduring part of KISS’s story.” They extended their condolences to Frehley’s estranged wife, Jeanette, his daughter, Monique, and “everyone who cherished him, including our global fanbase.”

Frehley passed away on October 16 at the age of 74. His family confirmed his death and reflected on his final moments in a heartfelt statement.

“We are utterly devastated and heartbroken. In his final moments, we were blessed to be able to envelop him with loving, caring, and peaceful words, thoughts, prayers, and intentions as he departed from this world,” the statement disclosed.

“We cherish all of his finest memories, his laughter, and celebrate his strengths and kindness that he bestowed upon others. The magnitude of his passing is of epic proportions, and beyond comprehension. Reflecting on all of his incredible life achievements, Ace’s memory will continue to live on forever!”

Frehley had been hospitalized on life support after falling in his studio and suffering a brain bleed just a few weeks before his death.

The “Cold Gin” rocker previously confirmed he suffered “a minor fall” in his studio that resulted in a trip to the hospital in a statement shared on his social media Sept. 25.

“He is fine, but against his wishes, his doctor insists that he refrain from travel at this time,” the message read in part. “Ace looks forward to continuing on his tour and finishing work on his next album, ‘Origins Vol. 4.’”

He later revealed in an October Instagram post that the remainder of his 2025 tour dates would be canceled due to “some ongoing medical issues.”

The guitarist was an original member of the famed rock band until he left in 1982. He went on to form his own group, Frehley’s Comet, years later before he ultimately went solo.

He notably had a contentious relationship with his former KISS bandmates after his departure. Though, he reunited with them in 1996 for a reunion tour that lasted until 2002.

Frehley collaborated with Simmons on several shows throughout the years — He previously joined Simmons for a Children Matter benefit in 2017 as well as for one of Simmons’ “Vault experience” shows at Capitol Records in Los Angeles in 2018.

However, he declined to join KISS for their End of the Road farewell tour, which featured OG members Simmons, 76, and Stanley, 73, along with Tommy Thayer and Eric Singer on lead guitar and drums.
