Olly Murs has revealed that he is a big fan of both new X-Factor USA judges Britney Spears and Demi Lovato.

The 28-year-old, who is gearing up to release his first album in the States in December, told MTV News that he thinks the ‘Womanizer’ superstar is ideally suited to the role:

"She's one of the biggest artists that we've ever had. What she's achieved musically is amazing and I think this just gives her a new string to her bow. And I think that if there's anyone that could judge someone on the 'X Factor,' she's qualified to do it.

“Let's be honest, also, she's had her ups and downs in the industry as well so it's going to be exciting to see how she copes with it all as well and how she gets on."

The 'Heart Skips A Beat' chart-topper, who this week unveiled the artwork for his third UK album, 'Right Place, Right Time,' also revealed he’s heard nothing but good things about the Camp Rock star from a certain boyband:

"Demi Lovato, I mean, I don't know too much about Demi, but hearing about her from the States and hearing about her from the likes of One Direction speaking about her, obviously she's a very lovely girl, fun. She's obviously a great singer and great performer as well.”
