You're never going to find them because the mothers are in on it,' she said Disturbing: Former lead singer of the Lostprophets and convicted paedophile Ian Watkins pictured in 2008 cuddling a sick child at a hospital in Wales Shocking images have emerged of paedophile rockstar Ian Watkins visiting sick children in a hospital. The Lostprophets singer, 36, went to see children at the University Hospital of Wales in Cardiff as part of his role as 'ambassador for young people' for the Kidney Wales Foundation. He was even greeted by the then Labour Health Minister Edwina Hart on the visit which was part of a campaign for more people to donate organs. Now photographs have emerged of the visit showing the paedophile smiling as he went to see boys and girls on their sick beds - leading to startling comparisons between him and convicted paedophile Jimmy Savile. At the time these images were taken, Watkins had already undertaken a string of sex offences which would lead to him attempting to rape an 11-month-old baby boy. Speaking at the time of the hospital visit in 2008, he said: 'I had a great time meeting all the kids at the hospital. 'Lots of the children are waiting for a kidney transplant, but there's a desperate shortage of donors. 'That's why we need more people to join the Organ Donor Register and help save a life one day.' Lostprophets even headlined a special one-off concert on New Year's Eve where he urged fans to sign the NHS Organ Donor Register. He added: 'I'm really proud to be the charity's new ambassador for young people and will be working with them on the Donate Wales campaign. We can continue to get more young people to sign-up. Watkins has now been stripped from his title by the charity after he admitted attempting to rape a fan's 11-month-old baby son along with 10 other child sex offences. Hospital visit: Ian Watkins, pictured at the University Hospital of Wales with his mother Elaine, was an 'ambassador for young people' for the Kidney Wales Foundation Message: Watkins visited ill children at Cardiff's University Heath hospital as part of his charity duties Shocking revelations: Ian Watkins had already committed a string of sexual offences at the time these images were taken at the hospital in 2008 Ian Watkins and his mother Elaine talk to the mother of one of the children being treated in hospital Kidney Wales has expressed its shock at the revelations. A spokesman said: 'The charity is appalled and stunned at the events involving Ian Watkins. Until his arrest the charity was never made aware of activities to which he was charged or any other activities which are now being investigated. Watkins got involved with the charity in 2008 because of his mother Elaine's on-going health problems. She had a kidney transplant two years ago and her condition is said to have been worsened by the revelations of Watkins sick child sex crimes. Past: Paedophile Ian Watkins was 'ambassador for young people' for the Kidney Wales Foundation in 2008 The shocking images emerged as a former prostitute girlfriend of the singer said he abused hundreds of young fans who are helping to hide the true extent of his prolific child abuse. Joanna Majic, 38, had a two year on-off relationship with the rock star from 2006, but dumped him when he told her his sexual fantasies revolved around child abuse. 'I've always said to the police, there's hundreds of victims out there and you're never going to find them because the mothers are in on it,' Miss Majic said today. She also says she warned police about the singer's depraved nature four years ago after he told her he wanted to have sex with a child, but says they refused to investigate it. Asked how she felt about his the outcome, she said: 'I don't feel happy about it. I don't feel vindicated. I'm just devastated that it took so long'. Miss Majic says Watkins, 36, wanted her to help him find a victim, so she went to South Wales Police but she claims they refused to investigate.

She said when police took no action against Watkins she contacted him and apologised on the assumption that her child abuse allegations had been wrong. Her intermittent contact with Watkins, however, would quickly prove that her worst fears had been true. On one occasion Watkins showed her a horrific video on his laptop which was so unpleasant she threw him out of her room. On another he sent her a picture of a little girl taken in his room who was holding a towel which had her picture printed on it. On that picture towel was a razor blade and a line of what appeared to be coke (cocaine). She had a rolled-up note. One year ago she went to the police again only to learn that he had now been arrested. 'They said 'Joanna we've already arrested Ian,' and I just said 'You're four years too late,' because if they'd have done something in 2008 he never would have done anything.'
