Former X Factor star Danny Tetley pleaded guilty to a series of child sexual exploitation charges by asking teenage boys to send indecent images to him for money.
Tetley reached the semi-finals of the ITV talent show in 2018 and finished sixth overall.
Tetley, of St Enoch's Road, Bradford, was brought from custody to the city's crown court and formally entered guilty pleas to five charges of causing sexual exploitation of a child relating to five teenage boys aged 15 and 16.
The 39-year-old's court case was previously subject to a court order preventing publication of his previous guilty pleas to similar offending, but today the Recorder of Bradford Judge Jonathan Durham Hall QC lifted the restriction after the singer admitted five more allegations.
It can now be reported that at a previous hearing Tetley admitted four other allegations understood to have involved similar offending with two 14-year-olds.
None of the victims in the case can be identified for legal reasons.
The charges he admitted today cover a period between October 2018 and August this year.
Prosecutor Michael Smith told the judge that the Crown would not seek to try Tetley on other outstanding allegations to which he had pleaded not guilty and the case was now ready for sentence.
Mr Smith said: "The investigation is complete and the victims have been identified."
Some of the charges faced by Tetley include allegations that he tried to induce two boys to send him indecent images which would be in the most serious category for such offences.
Barrister Andrew Dallas, for Tetley, asked for the sentence to be adjourned so that the defence had time to consider "well over 10,000" text messages or WhatsApp messages which had been served.
Tetley, who appeared in the dock wearing a black short-sleeve t-shirt and pale blue jeans, was remanded back into custody until next month.
Judge Durham Hall fixed the sentence hearing for January 24 next year and said the case would go ahead on that day barring an exceptional problem.
