Lostprophets frontman Ian Watkins has been remanded in custody after appearing in court to face child sex abuse allegations.
Watkins, 35, from Pontypridd, is alleged to have conspired with another woman to rape a one-year-old girl, Cardiff magistrates heard.
He also stands accused of two incidents of conspiring to engage in sexual touching with two young children; and possessing and making and distributing indecent images.
Watkins is also accused of possessing "extreme" animal pornography.
His lawyer, Tom Crowther, said the singer will be denying the charges.
Watkins, along with two women aged 20 and 24 who cannot be named for legal reasons, are due to appear before Cardiff crown court on 31 December.
The 24-year-old has been charged with the same offences as Watkins, while the 20-year-old woman is charged with five of the same offences but not conspiracy to rape.
