Let's get right down to it: Who does Simon Cowell think will be named American Idol this week?

The answer? Well, he just doesn't know.

"I can't call it at this stage," Cowell told reporters on a conference call. "For Blake Lewis, he's a brilliant entertainer, but the negative is he's not a fantastic singer. The advantage for Jordin is she is a great singer and the negative is she hasn't done one performance yet which I can remember as a 'wow.'"

Cowell also said he was amused by the long run of Sanjaya Malakar, a contestant known for extreme hairstyles and mediocre singing.

"The whole Sanjaya thing was hysterical," said Cowell, who once threatened to quit if Malakar won. "I don't think I'd be happy if he was in the final, but looking back I think it was quite amusing."

Cowell added it was "unfair" that contestant Melinda Doolittle was eliminated from the show this week.

"When you allow the public to choose, you've got to live and die by the vote," he said.
