While cruising through Beverly Hills in his chauffeur-driven Rolls Royce, Simon Cowell was more than willing to pull over and chat with us about all the drama that's surrounding X Factor this season, and he definitely set the record straight!

The music mogul confessed that Britney Spears and Demi Lovato are "doing the best they can" as judges, revealing:

    "I've worked with much harder. Honest to god they are doing the job we paid them to do, and they are doing a great job. They are both, albeit feverish, but we hired them for that. They are trying to find a star, and give constructive advice. They ought to be my mentor"

Cowell also revealed that Demi is a bit of a "brat," confessing: "She represents a younger audience and she's smart, but a bit of a brat. But I like brats." Though he had nothing but love for Britney, saying: "She's got amazing instincts, this girl. She could work for a record label; she knows how to spot a star. I am really impressed with her. She's smart, she knows what she's doing, and she wants to do a good job."

Simon added, "They've both been child stars. They want to find somebody else, and I'm very impressed with them."
