The married couple are going head-to-head on this year's show and while they love sharing their lives with each other, neither one of them is willing to give their 'X Factor' rival an advantage.

A source said: "They will do whatever it takes to win this show. It's definitely the battle of Mr & Mrs."

Rival judge Louis Tomlinson is extremely confident that he'll emerge from this year's show with the winning act.

And some of the judging panel - which also includes 'X Factor' boss Simon Cowell - have even been taking bets on the outcome of the current series.

The insider told the Sunday Mirror newspaper: "Louis Tomlinson is saying he will double the figure and he will be donating his win to charity.

"The show has never seen this amount of competition between the judges before, they are all set on winning."

The members of the judging panel are prepared to go to extreme lengths in order to triumph with one of their acts.

Another source added: "Who knows what lengths they'll go to, to make sure their contestants make it to the final?

"They all really care about their acts and want the best for them.

"It's great to see this competitive streak between the panel. They are definitely keeping everyone on their toes."
