The ex-husband and manager of Mexican singer Gloria Trevi has made his first court appearance in his home country.
Andrade appeared in court a day after his extradition from Brazil
A judge in the northern city of Chihuahua read out charges of rape and corruption of minors against Sergio Andrade - who was standing in a cage.
The 48-year-old defendant was extradited from Brazil on Friday.
Prosecutors say he and Ms Trevi abused girls who were travelling with them looking for musical training. They deny the charge.
Ms Trevi, 35, is being detained at the same prison as Mr Andrade.
The singer, known as the Mexican Madonna, was one of the biggest Mexican pop stars of the 1990s.
She is accused of involvement in procuring underage girls for Mr Andrade.
The prosecution's chief witness is Karina Yapor, who was 12 when she joined Ms Trevi as a backing singer in 1997.
She says she was abused while living with the couple and had a baby by Mr Andrade.
Trevi had a baby in prison
Another of Ms Trevi's backing singers, Maria Raquenel Portillo, is also accused of corrupting a minor.
Ms Trevi was arrested in Rio de Janeiro in 2000 and was in and out of jail in Brasilia while her home country attempted to bring her to face charges in a Mexican court.
During her detention, her baby Angel Gabriel was conceived and born. Mr Andrade was identified as the father.
She was extradited last December.
