Ian Watkins' former Lostprophets band mates have said their "hearts go out" to his victims after he pleaded guilty to a string of child sex offenses.

The disgraced rocker admitted to attempting to rape a fan's 11-month-old baby son and 10 other child sex offenses but pleaded not-guilty to the rape of an under 13 at Cardiff Crown Court this week.

The remaining members of the now-disbanded group have released a statement in which they said they are disgusted by Watkins' actions and their "hearts go out" to those affected. "Our hearts go out to Ian's family, the fans and friends he betrayed, and most importantly, the victims of his crimes and others like them. We hope for justice, but also that Ian will truly take responsibility for what he's done," they said In a post on their Facebook account.

The group also noted they are "disgusted" by what Watkins did behind their backs: "Many of you understandably want to know if we knew what Ian was doing. To be clear: We did not ... We are heartbroken, angry, and disgusted at what has been revealed. This is something that will haunt us for the rest of our lives. Being in a band has always been a labor of love and a platform to inspire people, not to take advantage of them. It's still hard to believe this is happening and that someone we were once so close to has destroyed so many lives, lying every step of the way."
