Ian Watkins' former Lostprophets bandmate Lee Gaze says the jailed singer was completely deluded about the future just days before his arrest.

The Welsh group disbanded after frontman Watkins was jailed for 35 years for child sex offences in December, but guitarist Lee has revealed Ian was ''strangely positive and enthusiastic about everything,'' on a video shoot before he was taken in by police.

He told BBC's Newsbeat: ''[He was] talking about the next record and how it's going to do really well and get back on our feet. It goes to show how deluded he was. He is just completely on a different level to everybody, happy and positive and convinced we were going to be successful again.''

Lee also insisted he and with former Lostprophets bandmates Stuart Richardson, Mike Lewis and Jamie Oliver - who have formed a new band No Devotion with ex-Thursday singer Geoff Rickley - had no idea about Ian's depravity.

He said: ''How could you know? How would anyone know? Who would disclose such a thing to five people, who between them have eight children? You just wouldn't because they would be killed on the spot.''
