Rock singer Ian Watkins has been labelled a "determined and committed paedophile" after he pleaded guilty to a string of sex offences, including the attempted rape of a baby.
The drug-crazed former lead singer with multi-million selling band Lostprophets plotted the abuse with two mothers in a text and internet messages.
These detailed his desire to "cross the line" and to intoxicate one of his victims by blowing crystal-meth smoke into the child's face.
Watkins (36) from Pontypridd, south Wales, pleaded guilty to a string of sex offences he had previously denied in a last-minute change of plea ahead of what would have been his trial at Cardiff Crown Court.
The charges included sexually touching a one-year-old and encouraging a crazed groupie to abuse her own child during a sordid webcam chat.
Watkins also admitted possessing and making child porn, as well as plotting to rape a baby.
The disgraced rocker was originally charged with rape but insisted sex with the child did not take place during a drug-fuelled binge he claims he was on at the time.
Watkins faced 24 separate charges, including two of child rape, but yesterday pleaded guilty to 11 charges, nine of which were unchanged, and two of attempted baby rape.
Prosecutor Christopher Clee told Mr Justice Royce both attempted rape admissions were accepted, partly to spare a jury the ordeal of having to watch sordid video evidence .
He then gave details of a sickening plot to turn babies in to sex abuse objects. He told the court: "Ian Watkins was the lead singer of a successful band called the Lostprophets.
"He was also a determined and committed paedophile engaged in serious sex offences involving of two babies."
Mr Clee read aloud a series of text and internet messages between Watkins and two female co-defendants.
Watkins and Woman A swapped messages where the frontman spoke of his sick desire to "make him mine" and to "cross the line".
They also spoke of plans to blow crystal-meth smoke into the child's face at a secret meeting in a Cardiff hotel. And on March 23, Watkins sent the woman a message saying he wanted a "summer of filthy child porn" and how he wanted to take things "to the next level".
Mr Clee also gave details of a sick 17-minute video involving Watkins and Woman A.
Mr Clee said camcorder footage was shot in a London hotel room which showed Watkins perform a sex act on the baby boy.
Mr Clee said that following this meeting, the pair exchanged emails about how they would not go "easy" on the child next time.
He also outlined a series of meetings between Watkins and the two female fans, who were the mothers of the baby abuse victims targeted by him.
Watkins also indulged in a depraved 45-minute Skype session in last October where he got woman B, aged 24, to abuse her baby in front of him.
Mr Clee added that when police raided Watkins' home after his arrest last September, they also found a box of camcorder cassettes of filmed sex acts with underage girl fans, one of whom he met up with in a New York hotel.
As sentencing arrangements for December 18 were discussed, a pale-faced and grey-haired Watkins began shaking in the dock.
