Kelly Rowland has warned X Factor judges Britney Spears and Demi Lovato that Simon Cowell will blame them if anything goes wrong.

The Destiny's Child hitmaker spent one season on the panel of the UK version of the show, and although she loved the experience, she admitted it can be tough.

"I'm excited for them. I'll let them know it's a lot of work. It is a lot of work, but it was definitely a great process. It is a lot of responsibility, and when you screw up or if you screw up, then everybody blames you. Simon included," she told MTV News.

However, Kelly loved having the opportunity to take part in finding the next big thing and thinks Britney and Demi will do a great job on the US series: "You might be running into the next big thing. Or, like for Britney, the next big her, or the next big Demi Lovato. I think that's really exciting for them, and they'll be a part of that, and they'll never forget that."
