MILAN, Italy - George Clooney and his ex-girlfriend Elisabetta Canalis are among some 200 witnesses accepted by a Milan court in the trial of former Premier Silvio Berlusconi on charges of underage prostitution.

Italian news agency said the court accepted defence and prosecution witness lists Wednesday.

Clooney has said he was approached by Berlusconi's team to testify about parties at Berlusconi's villas, but says he only visited the premier's residence once to seek aid for Darfur and declined an invitation to stay for a party. His inclusion on the list does not necessarily mean he will testify.

The witness list also includes Karima el-Mahroug, the Moroccan teen who is alleged to have had sex with Berlusconi in exchange for money. Both she and 75-year-old Berlusconi have denied a sexual relationship.
