Former JLS member Oritse Williams has been charged with rape.
The charge comes after an alleged attack on a female fan in a hotel room after a concert.
The 31-year-old singer, from Croydon, London, was arrested on 2 December 2016.
Since leaving JLS, he has embarked on a solo career and the arrest was made the morning after he performed at the Gorgeous club in Wolverhampton.
Another man, Jamien Nagadhana, 31, of Hounslow, London, faces a serious sexual assault charge.
The pair are due to appear before magistrates on 11 October.
Mr Williams denied the accusations in a statement released through his management at the time of his arrest.
