Lambert, who competed on season eight of the singing competition, said he wouldn't mind taking a seat at the judging table himself.

"That would be fun," he shared. "I just judged X Factor in Australia last year and I had a blast."

"I really liked working with talent," the 35-year-old singer continued. "I had, like, the young group and it was great to, like, develop their acts and their songs and help them get where they wanted to go, so yeah, I'd be game."

"I am honored and thrilled to be the first judge bringing back the American Idol tradition of making dreams come true for incredible talents with authentic personalities and real stories," she said after the announcement. "I'm always listening to new music, and love discovering diamonds in the rough - from mentoring young artists on my label, or highlighting new artists on my tours, I want to bring it back to the music."
