"So far everything has been so fun for all of us," Britney Spears says of being a new judge on The X Factor in a new promo (watch below). "Everything is like a new experience for me, so it's a lot of fun and the talent has been amazing."
Spears, who's been called "incredibly tough" on the show, is seen in the promo telling a contestant, "I wanna know who let you on stage."
"I feel like my judging style is very subtle," she says. "I try to use constructive criticism."
Spears will sit alongside show creator Simon Cowell, returning judge L.A. Reid and fellow newbie Demi Lovato.
"The most fun about being on The X Factor is seeing people that really wow you and knowing that you saw them before they were going to become stars," Lovato says. "It really is an exciting feeling."
As for her judging style, "I would say that I'm a happy judge," Demi says. "I'm really, really honest. That's the great thing about this panel – we're really honest."
Season 2 of The X Factor premieres Sept. 12 (8 p.m. ET) on Fox.
