Howard Stern wants to see the "train wreck" Britney Spears is on The X Factor. The 58-year-old America's Got Talent panelist said that the 30-year-old pop star's appearance will be gripping viewing because of her level of intelligence.

"I think it's a wonderful decision. Britney still thinks the earth is flat," the outspoken longtime radio presenter said.

Speaking at a press conference at New York's Friars Club on Thursday, Howard joked that Britney - who is a mother of two children - may not be able to function at her new job where she will replace either Paula Abdul or singer Nicole Scherzinger: "I can't imagine... I think we're going to tune in to see her, to see if she can function through the thing."

The controversial talent show judge added, As far as any real criticism, I think Simon[Cowell] and LA Reid will do that. As far as criticism, I think Britney will sit there and eat a lollipop and wear a sexy outfit... I'll tune in to see what kind of train wreck she is, absolutely."
