'American Idol' Ruben Studdard thinks Simon Cowell is irreplaceable

Ruben Studdard, "American Idol" winner from Season 2, thinks "nobody" can replace judge Simon Cowell, whom he calls "an original."

And as far as picking a new male or a female judge, "it don't matter." The only thing he knows is that they need to pick "somebody good."

Ruben says that although Simon is always brutally honest, he's also the nicest person you will ever meet. And yeah, he'll probably give him a hug after the show tonight and wish him well.

Give him a hug from us too, Ruben.
