'Idol' Lookalikes: Separated at Birth

Vin Diesel & Chris Daughtry

The resemblance is astounding -- creepy even. Check out these 'Idol' singers and the celebrities (and cartoon characters) they look like.
Double-Take: Maybe it's the matching bald heads and five o'clock shadows. But get Vin a guitar and give Chris some protein shakes, and you'd have a dynamic duo.

Kevin Covais & Chicken Little

Double-Take: Fellow season five contestant Paris Bennett gave Covais the nickname "Chicken Little," and it stuck -- with good reason.

Katharine McPhee & Katie Holmes

Double-Take: One is a Scientologist married to a guy twice her age. The other took Scientology classes and is dating a guy twice her age. One is named Kat, the other -- Kate. That's just creepy.

Sade & Christina Christian

Double-Take: Though it pains us to give him credit, Simon was spot-on when he compared the Brooklyn-born season one finalist to the '90s soul singer.

Clay Aiken & Barry Manilow

Double-Take: The likeness doesn't stop at just looks. The music, the fanbase, the swirling rumors about their love lives -- it's as if Aiken is modeling his whole career after Manilow's.

Corey Clark & Sideshow Bob

Double-Take: You thought we'd go for the Sideshow Bob / Justin Guarini comparison, right? Relax, Guarini's coming up later. Plus, Clark and Bob have more in common: they are both sleazy villians.

Jared Cotter & Brian McKnight

Double-Take: Paula said it first, and for once she was right. Cotter evoked comparisons to the top R&B crooner with his modelic looks and soulful song choices.

Mulan & Jasmine Trias

Double-Take: You can bet that Trias, now an A-list star in the Philippines, would be the first considered if Disney were to take 'Mulan' to Broadway. (Not that we'd want to see it, but still.)

Jordin Sparks & America Ferrera

Double-Take: Considering those plucky attitudes, the sparkle in the eyes and the wide-mouthed grins, how can you not just love them both?

Justin Guarini & Will Ferrell

Double-Take: With Ferrell sporting long hair for his latest movie role, Guarini knows what he has to look forward to in about 20 years.

Lakisha Jones & Kelly Price

Double-Take: These two plus-sized divas have mighty voices and huge stage presence to match.

Mikalah Gordon & Fran Drescher

Double-Take: Gordon landed a guest-starring role on Drescher's short-
lived sitcom, 'Living With Fran.' She was cast as the comedian's cousin, but she could have easily played her daughter.

Nikki McKibbin & Joan Jett

Double-Take: McKibbin started the token "rock chick" role that's become so commonplace on 'Idol.' But she clearly took influences from trailblazers like Jett.

Stephanie Edwards & Tamyra Gray

Double-Take: The two Georgia natives have the same tastes in style and song choice, and they even have similar personalities. Are we sure Tamyra didn't enter the competition again under a different name?

Taylor Hicks & Michael McDonald

Double-Take: Hick's Michael McDonald-esque voice helped him break away from the season five pack, but the gray hair keeps the comparisons going.

Chris Richardson & Justin Timberlake

Double-Take: It would be unfair to call Richardson a Timberlake wannabe. He can't help that he looks and sings just like him. Instead, we'll call that a winning strategy.
