Sounds like the plot of a dark George Clooney thriller.

On Tuesday, the Oscar-winning actor was named a potential witness -- along with his girlfriend Elisabetta Canalis and dozens of prostitutes-- in a shocking sex trial against Italian prime minister Silvio Berlusconi.

In April, Berlusconi, 74, goes on trial for allegedly paying for sex with an underage girl last year. Berlusconi's young accuser, a Moroccan girl named named Karima el-Mahroug, claims she saw Clooney and native Italian Canalis at a dinner party held at the head of state's home; Clooney, 49, has a nearby home in Lake Como.

"We want to see if they confirm this fact or not," attorney Piersilvio Cipollotti told the Associated Press.

But Clooney is dumbfounded by his inclusion on the potential witness list. "It seems odd since I've only met Berlusconi once and that was in an attempt to get aid into Darfur," he said in a statement to the Associated Press.

The Associated Press reports that Canalis has already spoken with Italian authorities and has denied ever attending one of the premier's dinner parties.
