Demi and Britney stop for photos at the auditions in San Francisco.

The US X Factor will kick off the season this year for Fox and the show adds Britney Spears and Demi Lovato to the judge’s table for the 2012 season.

The show will get a two-night premiere starting on Wednesday, Sept. 13 and an hour-long episode will follow the next day.

What will we see for this season's show?

It might be the blame game.

Certainly lots of acts both good and bad will appear on the Fox reality TV show and when things all go really wrong, one-time UK X-factor judge Kelly Rowland has warned 'X Factor' judges Britney Spears and Demi Lovato that Simon Cowell will blame them.

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.

She told MTV News: "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."

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.

She said: "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."
