Silvio Berlusconi's defense lawyers want George Clooney and his Italian girlfriend to testify at the premier's upcoming prostitution trial.

Berlusconi is accused of paying for sex with a 17-year-old Moroccan girl and using his influence to try to cover it up. He denies wrongdoing.

The trial opens April 6 in Milan. On Tuesday, prosecutors and defense attorneys presented their lists of witnesses to the court. A judge must now decide which witnesses to admit.

The law firm representing Berlusconi says Clooney was listed because the Moroccan teenager once said she had seen Clooney and girlfriend Elisabetta Canalis at one of Berlusconi's parties.

Canalis has reportedly denied attending.

An email sent to Clooney's representative wasn't immediately answered.
