However, Kelly joked in a previous interview that she wouldn't have minded coming in second place to Justin Guarini because she didn't want to do the From Justin to Kelly movie. "I don't like to lose, let's be real," she told Entertainment Tonight. "The reason why I didn't is because I found out, Justin and I both found out that last week, that whoever won had to do this movie."

Will Kelly Clarkson be on the American Idol reboot?

Kelly decided to join The Voice over American Idol, and in a recent interview, she explained why. "I've been in talks with The Voice about doing stuff for years," she previously shared with Entertainment Tonight. "It's a family decision too, for us. Like, my husband, [Brandon Blackstock], manages Blake [Shelton] so we're all in one place and it's going to be good. And I'm excited, y’all."

She added to Entertainment Weekly, "We’re used toThe Voice schedule, we already have to work around it because of our family. We have four children — that can be very taxing with a schedule. It was just a no-brainer for me with The Voice because of that alone. But my thing is, I was kind of bummed too when [Idol] came to me. I hope it’s super successful."

She notes it would have been great to work on the Idol reboot with pal Ryan Seacrest. "Would it have been awesome to come back to the show that started me and help give someone that start? Yes!" Kelly confessed. "But that doesn’t mean I can’t do the same thing on The Voice. That’s my goal. I want to have someone on my team, whether they win or not, to have a successful career after being on the show."
