Demi Lovato has officially been named host of the 2012 Teen Choice Awards, EW reports.

The former Disney star and current "X-Factor" judge will take charge of the teen awards show, which promises a performance by Carly Rae Jepsen and appearances by Zooey Deschanel, the "Glee" cast, Ellen Degeneres, Kristen Bell and more.

Lovato re-entered the TV spotlight after she was named an "X-Factor" judge in May.

"I'm totally stoked to be here ... I'm excited to represent my generation and find the winner!" she said at the Fox upfront presentation, where the network revealed what's to come for the 2012-2013 TV season.

With a couple months of auditions behind her
, Lovato admits her judging duties aren't always easy. "It's really hard for me to smile if they're performing and they're horrible," she told Access Hollywood. "I have to be super super honest and sometimes I feel bad about it."

The 2012 Teen Choice Awards air on Sunday, July 22 at 8 p.m. ET on Fox.
