After Kelly Clarkson gave us all Access last year to the making of her “Behind These Hazel Eyes�? video, we thought we’d see what the very first “American Idol�? winner was up to!

Kelly graciously opened up her life to Access again and this time, she showed about 1,500 people exactly what she’s made of.

Access first nabbed a rare glimpse of Kelly in her native habitat doing vocal warm-ups just moments before she hit the stage.

“I was just like, don’t screw it up,�? Kelly laughed. “First verse, second verse. I was sitting there, running it through my head.�?

Prep time came first though, not with a team of hair and makeup artists fussing over Kelly but a single stylist.

And their conversation? Not what you’d expect from a Grammy winner.

“My sister and brother-in-law are going to museums today,�? Kelly said. “I am so jealous!�?

With Kelly, you can forget about a backstage entourage or diva demands.

The only remotely rock star thing about her?

“I have Adam,�? Kelly told us. “He’s my trainer. He’s on tour with me. I do kickboxing. I have bruises on my legs right now because of the pads!�?

Unlike other young stars, the fit former “Idol�? does not give in to Hollywood’s trend toward the superskinny.

“Oh, well, child, I’m in the industry,�? Kelly told us. “People put pressure on me every day. So you get pressure left and right. But I eat what I like. I work out because it’s good for my body. It’s not like I do it for other people.�?

Kelly casually surveyed the empty stands at the Ford Amphitheatre in Tampa, Fla. that would soon be filled with eager fans.

She was plotting a little walk through the audience!

“Well, I don’t want to do the same thing every night because fans will be like — she’s gonna be in the middle!�? Kelly laughed.

Access was on hand as Kelly’s plan went off without a hitch. Kelly joined the crowd later that night as she serenaded them with “Hazel Eyes.�?

“It was great. It ended up being great,�? Kelly told us. “It was kind of nervewracking, though.�?
