The rocker denied rumors that he had an affair with Miley Cyrus's mother, Tish, who last month split from Billy Ray Cyrus after 17 years of marriage.
When asked on Fox & Friends if he'd had an affair with Tish, Michaels replied, "The answer is no."
"I've been friends with her family forever," Michaels added. "It started out with me and Miley simply working on a song together. Her mom, Tish, likes "Every Rose Has Its Thorn," the first concert Miley ever saw was Poison, and so they wanted to remake it for the new record."
Reports surfaced last week that the Poison frontman was the possible cause behind the Cyrus divorce. Last month, Billy Ray filed divorce papers in Tennessee citing irreconcilable differences.
Michaels insists his involvement with the Cyrus family has been strictly professional. "When I was in the studio, Miley came in and sang on my song … and that was it," he said.
As for how Miley's taking her parents' divorce? A source close to the singer told PEOPLE last week, "she's trying to keep everything private while her family works through this."
