Ayda Field is looking forward to working "together and against" her husband Robbie Williams on 'The X Factor'.

The couple have both signed up as judges on the ITV talent show and Ayda has quipped that she had to agree to take on the role because Robbie would be "lost" without her.

Speaking at the press conference to launch this year's 'X Factor', she said: "I was surprised and excited. On a professional level I've auditioned for years. I know what it's like to get the job and I know what it's like to lose the job. I have a huge amount of empathy for the process. Without me, Robbie would be lost. I'm really excited the fact that means we get to work together and against each other, I'm really excited."

And Robbie thinks the American actress and 'Loose Women' star - with whom he shares five-year-old daughter Teddy and three-year-old son Charlton - has been a huge part of her career but joked it may not be plain sailing for them on the show as they don't always agree.

Robbie quipped: "How big has Ayda been in my career? Well ... the first five albums were my biggest. She's been my rock and helps me through the thickest and the thinnest. I go with her opinion 95 per cent of the time. Unless we're on a TV show, and then maybe not."

'The X Factor' returns with an all new judging panel - Ayda, Robbie, One Direction's Louis Tomlinson and Simon Cowell - later this year.
