The rumor mill really went to work regarding Miley Cyrus' parents' relationship back in 2010.
A few weeks later in November 2010,Us Weeklypublished that it was because of infidelity.
Reportedly, Cyrus-Purcell and Bret Michaels from the band Poison had an affair.

“Billy Ray was completely unaware of what was going on,” the insider said.
Cyrus-Purcell’s representative said the same, but the source for Us Weekly was adamant it was true.
“But here’s the thing, I’ve been friends with her family forever.

It started out with me and Miley [Cyrus] simply working on a song together.”
Then, Miley sang with Michael on his song “Nothing to Lose.”
“And honestly, that was she did a beautiful job,” Michaels said.

“And then, that was it.
You know, and they started with all that controversy, so.”
However, Cyrus-Purcell and Billy Ray did eventually get divorced in 2022.
The couple did in October 2023.
Bret Michaels has had his fair share of on-and-off romances.
They still co-parent their daughters Raine and Jorja Michaels.
Michaels toldPeoplein 2023, “We’re great parents together, and we sincerely love our kids.”
