Bo Bice and Vonzel Solomon brought down the house Tuesday night on "Idol," while Heather Locklear and her adorable daughter, Eva, watched from the audience. Today our Terri Seymour got the inside scoop on the final six from the one and only Simon Cowell.

The Rockers: Bo and Constantine
"If I wore eyeliner and pouted would I be more attractive?" Simon asked sarcastically. "I don't believe any of these guys are rock and roll, and I'll tell you why: can you imagine the lead singer of Green Day singing 'I Can't Smile Without You' with Carrie Underwood? I mean give me a break."

Carrie Underwood
"There's a movie called 'The Mighty Wind,' and it's about a folk group reuniting," Simon recalled. "And I looked at Bo and Carrie and I thought, 'God, this is like a scene from The Mighty Wind.'"

Anthony Fedorov
"He's a little angel," Simon admitted. "It's only when he does that Latin dancing, it's, 'Oh shut up, Anthony!'"

Vonzell Solomon
"Definitely the most personality," insisted Simon. "Very, very sweet person."

Scott Savol
According to Simon, "Scott epitomizes the normal guy who can do well in this competition. I think he's the sort of person who all his life has been told, 'You can't do this, you'll never achieve that.'"

So Long to...
So who will get the axe tonight? Simon made the call: "It's going to be difficult to predict right now, but my money would have to be on Scott."
