an Watkins, singer of Welsh rock band Lostprophets, has pleaded guilty to a series of "depraved" child sex offences including attempted rape of a baby.
He had previously "furiously denied" the allegations.
The 36-year-old from Pontypridd and two women had been due to stand trial at Cardiff Crown Court.
Watkins pleaded guilty to attempted rape and sexual assault of a child under 13 but not guilty to rape. This was accepted by the prosecution.
Sentencing will take place on 18 December.
Prosecuting barrister Chris Clee QC told the court: "Ian Watkins was the lead singer in a successful band called the Lostprophets.
"He accepts he was a determined and committed paedophile."
