'American Idol' Alum Justin Guarini Isn't Sure Adam Lambert Will Win

'It's time for everyone to step up,' he tells the top three.

Back in 2002, Justin Guarini came in second to [artist id="1231768"]Kelly Clarkson[/artist] during the first season of "American Idol." Now, the singer and TV personality has some advice for this year's top three: Adam Lambert, Danny Gokey and Kris Allen.

"I think it's going to be very interesting, 'cause everyone assumes Adam will go to the finale," he told MTV News. "The competition this week will be Danny and Kris trying to make it as well."

Although fans (and Simon Cowell) have their money on Adam, Guarini warns that anything can happen. "At this point in the game, you never ever know," he said. "I think that if Adam keeps doing what he does best, then he has a great chance to go to the finale. Now, really, it's time for everyone to step up."

"Idol" fans have had mixed reactions to Kara DioGuardi joining the judging panel this year, but Guarini thinks she adds a little bit of spice to the show. "I think she's great. I think she's a great mix of the other judges on the panel," he said. "She gives great advice from many points of view, as an artist and songwriter."

The final three are only a week away from learning who will be crowned this year's American Idol, and Guarini still can't believe that fallen contestant Alexis Grace didn't get a better shot on the show. "You know the most surprising thing for me has really been the early exit of Alexis," he said. "I think she went way too early, far too early. I think she deserved to be on the tour."
