Jennifer Lopez feels "a little scared" for new The X Factor judges Britney Spears and Demi Lovato - even though she thinks they'll "do great".
After months of rumours, the two pop stars confirmed they will be joining Simon Cowell and L.A. Reid on the judging panel of the hit American TV talent show on Monday.
American Idol judge Jennifer thinks the new additions will be a joy to watch.
"Just be yourself. I think it's just about really being your true self, not trying to be something that you're not," she told ET Online, when asked what advice she would give the show's new recruits.
"I feel a little scared for them 'cause I was scared when I started. It's live TV - there's a lot of pressure that goes with it - but I think they'll do great."
Jennifer is currently starring in What to Expect When You're Expecting alongside Brooklyn Decker. Her co-star says Britney's appearance on the show may encourage her to tune in.
"I saw [Britney] when I was 13," Brooklyn said.
"That was actually my 13th birthday present from my mom, was to go to a Britney Spears concert. So, I could see myself watching her [on the show]."
