L.A. Reid Talks Mariah Carey's Idol Move & Britney Spears On X Factor: I Get Why Brit 'Is So Loved'

L.A. Reid has been working alongside Britney Spears for the past few months as the pair judge contestants on “The X Factor,” and the music mogul says he’s become a huge fan of the pop star.

“Anytime you do something new it takes a second to get adjusted, but she’s a star. So she went into her – what I call – her star gear,” L.A. told Billy Bush and Kit Hoover on Thursday’s Access Hollywood Live in New York City. “She went into her star gear at a certain point and I was like, ‘Oh my God. Now I get it!’

“Now I completely get why this girl is so loved,” he added. “She’s amazing.”

And L.A. was quick to clarify that while the “Till The World Ends” is a sweetheart, she’s takes no prisoners when it comes to judging.

“Britney is tough! She’s honest, she’s tough, she doesn’t give you fluff,” he said. “She doesn’t just talk for the sake of talking – she tells you exactly how she feels. She’s pretty spot on – she’s got good taste.”

L.A. recently lent an experienced ear to another legendary music diva – his close friend Mariah Carey, who sought his advice before signing on to judge “American Idol.”

“[Mariah and I] had a great conversation about it and I advised her that she should do it,” he said. “I think it’s great for her.”

See L.A. in action – along with Britney, Demi Lovato and Simon Cowell – when “The X Factor” premieres on September 12 at 8/7c on FOX.
