Billy Ray Cyrus regrets becoming a friend to his children, insisting he "should have been a better parent" to Miley and her siblings.
The country star has always been close to his children, Miley, Braison and Noah, as well as estranged wife Tish's kids - Brandi and Trace - from a previous relationship.
Cyrus has often accompanied the Hannah Montana star to red carpet events and the teen star has previously admitted they enjoy a relaxed relationship.
But after watching Miley become embroiled in a string of scandals in recent months, including controversy over video footage showing her smoking a legal high from a bong, the Achy Breaky Heart hitmaker admits he now wishes he had been more firm with her when she was growing up.
He tells GQ magazine, "How many interviews did I give and say, 'You know what's important between me and Miley is I try to be a friend to my kids'? I said it a lot. And sometimes I would even read other parents might say, 'You don't need to be a friend, you need to be a parent.' Well, I'm the first guy to say to them right now: You were right. I should have been a better parent."
