Report: Bret Michaels Busted Up Miley's Parents

News that Miley Cyrus' parents Billy Ray and Tish were calling it quits after 17 years of marriage took many by surprise, but fans may find a new bombshell even more shocking: Billy Ray broke it off when it was revealed Tish cheated with Bret Michaels, reports US Magazine.

The 47-year-old former Poison frontman had become close to the family last year, after he and Miley released the duet "Nothing to Lose," and the magazine reports he and Tish began seeing each other behind Billy Ray's back soon after. US also reports Tish also cheated on the country singer and Hannah Montana patriarch with a second as-yet-unidentified person.

Reps for both the Rock of Love star and Miley's mom deny their relationship was anything but professional. Billy Ray filed for divorce October 27th, reportedly after he found out about the affairs.
