Britney Spears, Demi Lovato And Simon Cowell Chat About Their Chemistry On The X Factor

Britney Spears, Demi Lovato, Simon Cowell, and L.A. Reid pose together in the latest promo pics for The X Factor, and just yesterday the judges sat down at the Fox 2012 Summer TCA Tour to chat about what it's like working with one another.

“She’s a really, really good judge,” Simon said of Britney. “[She's] quite mean, as you’ll discover." Of course, Demi defended her co-worker, telling the audience, “She’s a sweetheart, who’s very honest." Simon's retort? "As sweet as a lemon!"

Simon added, “Demi is a brat, but there’s something very likable about her as well.” He noted that the 19-year-old pop star is good for the panel because they needed, “somebody a bit younger, because I’m in my 30s.” (For the record, Simon is 52!)

One reporter asked Demi what she brings to the table as a judge, and she replied, “I think that the expertise that I’m able to contribute is I’m listening to the radio right now and I know a lot of what my friends like, and we’re in our early 20s and late teens,” she said. “I think we know what is needed in this industry and what is missing."

So how did Britney land the gig, which earns her $15 million per season? “Actually, my makeup artist was the makeup artist for Simon,” she said. “We just all met up and it made sense. I adore Simon and it was something I really wanted to do."

Simon also revealed that there will be not one but two hosts next season, and they will be announced next month.
