Kelly Clarkson made her third appearance on sketch comedy show 'Saturday Night Live' last night (7th Jan 2012). Kelly Clarkson was the musical guest on the show, taking the stage twice in order to perform her smash-hit 'Mr Know It All' and her new single 'Stronger (What Doesn't Kill You)'.

The show was hosted by NBA Hall of Famer Charles Barkley who introduced the starlet on stage. In a recent interview with MTV News, Clarkson spoke about how she had been excited about returning to the NBC show again: "I'm a three-peat! I've made it. It's a legendary stage! I've been watching it since I was a kid. I think we all have. 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.' When looking back on her first appearance in 2005, when she was first 'American Idol' winner to grab a guest spot, Clarkson remembers getting to perform in a comedy sketch 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.'

Kelly Clarkson is currently promoting the second single, 'Stronger (What Doesn't Kill You)', off her fifth studio album 'Stronger'.
