Rock singer Ian Watkins was today described as a 'determined and committed pedophile' after he admitted attempting to abuse a fan's 11-month-old baby son along with 10 other child offences.

Watkins, 36, lead singer of the Lostprophets, changed his plea at the start of his trial this afternoon, but claimed he could not remember the 'depraved' abuse because he was high on crystal meth.

The singer - a former boyfriend of BBC radio and television presenter Fearne Cotton - pleaded guilty to offences involving the babies of two women fans.

He pleaded guilty to attempting to abuse the 11-month-old baby of a fan 'Woman A' and conspiring to abuse the baby daughter of another fan 'Woman B'.

The two fans, both in their twenties and from different parts of England, are also facing jail after admitting their role in the offences on their own children.

Cardiff Crown Court heard Watkins was videoed committing the depraved acts and was 'clearly identifiable' because of his many tattoos and his voice.

But Watkins claimed not to remember doing it because he was a 'heavy user' of class A drugs including Crystal Meth at the time.

Watkins spoke only to enter his pleas as he admitted attempting to abuse the baby.

The singer, dressed in a three-piece dark blue suit, also admitted assaulting the baby by touching him..
