Miley's mom had an affair with Bret Michaels

Oh shiiit!  US Weekly is reporting the reason Billy Ray and Tish Cyrus are getting divorced after 17 years of marriage is because Miley's mom had a piece of Bret Michaels on the side... HAHAHA!

It all supposedly went down back in February when Billy and Tish's superstar daughter recorded a duet with the Poison frontman... and that's when Tish decided to take a ride on the Rock of Love bus.  I guess the couple didn't have a prearranged list of celebrity freebies they were allowed to bang without it being considered "cheating"... so when Billy Ray found out, he quit his marriage.



I wonder how many marriages Bret Michaels has ruined in total??
