Simon Cowell

Simon Cowell has picked his favorite American Idol contestant of the season — and it comes as no shock that it's season-long front runner Adam Lambert

"I would have to put my money on Adam right now," Cowell told Oprah Winfrey during a guest appearance on her talk show Monday. "I think he's got that 'it,' and I think he's fearless and I think he's unique. And he's got swagger."

The episode also featured Britain's Got Talent superstar Susan Boyle, who answered Winfrey's question about whether she would get a makeover before her appearance on the Talent semifinals this month. "Depends what you mean by a makeover," Boyle said. "My best friend helps with my makeup. That's hardly a makeover."

When Winfrey inquired about her hairstyle change, Boyle downplayed her new 'do. "That was just to tidy myself over like any female would've done," said Boyle.

Do you think Cowell's Idol winner prediction will prove true?
