Simon Cowell and Britney Spears Guest Star on Jimmy Kimmel

Simon Cowell and Britney Spears appeared on Jimmy Kimmel to discuss the X Factor. Kimmel told Britney she was a tough judge. Britney said it wasn't a bad idea to perform one of her songs in front of her, but Cowell disagreed. Cowell says it's a bad idea because they tend to butcher her songs. Britney said she thought Cowell was a rude person before she met him.

Britney said she liked being a tyrant on the show. Britney said, "I would want to know. I wouldn't want to waste seven years of my life when I should be a doctor. It's giving good honest constructive criticism."

Cowell really needs to keep his shirt buttoned all the way up. Part 3 of the interview can be found here. Take a look:
