Former JLS member Oritse Williams has been charged with rape over an alleged attack on a fan in a hotel room after a concert.
The 31-year-old singer from Croydon, London, was arrested on 2 December 2016, the morning after performing at the Gorgeous club in Wolverhampton.
A second man, Jamien Nagadhana, 31, of Hounslow, London, faces a serious sexual assault charge.
Both men are due to appear before magistrates on 11 October.
At the time of Mr Williams’ arrest, a statement released through his management said he denied the accusations.
The singer enjoyed chart success with JLS after featuring on the X Factor in 2008.
Mr Williams then began a solo career when the pop group disbanded in 2013.
