Bret Michaels‘ camp denies a report the rocker had an affair with Miley Cyrus‘ mom, Tish, while she was married to singer Billy Ray Cyrus. “This is someone stirring a pot. This is untrue. He respects the family and worked with Miley and Tish on a professional level,” said Michaels’ rep. Reports claim that Michaels became close with the Cyrus clan after he and Miley recorded a song together, “Nothing to Lose.” Tish and Billy Ray are splitting after 17 years of marriage and filed for divorce last week.
