JLo is worried for the X Factor newbies
JLo - who took up the role of judge on American Idol back in 2010 - also told the singers to be themselves. When asked if she had any advice for the pair, she said:
"Just be yourself. I think it's just about really being your true self, not trying to be something that you're not."

JLo added that she felt a little "scared" for the two stars because of the demands of live TV.
She said: "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."
After months of speculation Britney Spears and Demi Lovato were added to the X Factor panel, with Britney signing a reported $15 million for the role.
