The Brazilian-born rapper, real name Yuri Santos, appeared on the most recent series of ITV's jungle-based reality show. Santos went on to finish sixth in the competition.
One of the charges dates back to accusations made against Santos and another man in May. Two women, ages 17 and 18, said that they were sexually assaulted in a Chichester hotel.
"The Crown Prosecution Service has authorised Sussex Police to charge a man in relation to two separate investigations of rape in Somerset and Sussex and a second man in relation to the offence in Sussex," Sussex Police said this afternoon.
"Yuri Santos, 22, of Bickersteth Road, London, has been charged with two offences of rape; one in Chichester on 7 May, 2011, and another in Yeovil between 25-26 September last year."
Both Santos and Ritchie have been bailed to appear before Chichester Magistrates Court on September 19.
Santos reached number eight in the UK charts with 'Like U Like', which featured Girls Aloud star Kimberley Walsh.
