Who are your fashion influences?
I’m inspired by Kiss, Alice Cooper, Sly Stone, and Elton John—people who have great showmanship. I just like to shake things up and breathe some fresh air back into music.Who’s your biggest competition on The Voice this season?
I don’t really look at my fellow coaches as competition because we’re all completely different. I’d love to trade places with Christina [Aguilera] to see what it feels like to sing as brilliantly as she does. Blake [Shelton] is down-to-earth, charming, witty, charismatic. I’ve grown very fond of him. And Adam [Levine] and I are friends, too. He’s just supercool.What is your Twitter philosophy?
Sometimes less is more! I make sure that it’s significant and filled with a sense of humor. I’m a people person, so it comes easily to me. It’s my passion.
