This weekend, Kelly Clarkson is making her third appearance on "Saturday Night Live" as the musical guest. But the bubbly singer insists that being a part of NBC's iconic show will never feel old hat.

"I'm a three-peat! I've made it," Clarkson exclaimed to MTV News when we caught up with her at rehearsals. "It's a legendary stage! I've been watching it since I was a kid. I think we all have."

More so than the enormity of playing Studio 8H, Clarkson said she digs the vibe of the cast and crew. "It's a fun environment. You don't feel like you're working ... This is like a family place. Everybody here is nice to people who aren't famous. You know what I'm saying? They're nice to my makeup artist, my hair guy ... I hate people who are just nice to famous people. It bothers me. I want to kick 'em," she chuckled.

Clarkson still thinks about her first appearance on "SNL" in 2005, when she became the first "American Idol" winner to snag a musical guest spot. Even cooler, she got to flex her comedic muscles in a couple of skits with former cast members Amy Poehler and Horatio Sanz. "I remember I was so excited. First of all, Horatio? He's hard to do skits with because you laugh 'cause he laughs all the time at [himself]. So you're laughing 'cause he's laughing, and I'm trying to keep a straight face. I had so much fun."

But this go-around, Clarkson's too busy to participate in any sketches, even though the politically charged "SNL" could write comedy gold for Clarkson, who recently found herself in the middle of the presidential race when she casually tweeted about digging Ron Paul's campaign. The singer's always down to poke fun at herself and be goofy, but alas, tour rehearsals are top priority. "We're literally flying in and out [of New York]. Charles Barkley's hosting, so he's doing all the skits."

Kelly fans can still look forward to two high-energy performances. During Saturday night's show, Clarkson and her band will rock her #1 single, "Mr. Know It All," as well as her latest hit, "Stronger (What Doesn't Kill You)."
