It has since been reported that Lisa could make £155 million from their divorce, and according to reports she has been advised to go after her presenter partner's future earnings.

It was previously said that Ant was willing to pay Lisa, 41, half of his £62million fortune to end their marriage amicably.

Yet The Sun reports that the make-up artist is said to have been told to follow in the footsteps of Karen Parlour - the ex-wife of Arsenal star Ray Parlour - who was awarded a third of the footballer's future earnings when they divorced in 2004.

An insider said: '[Lisa] is not motivated by money and she has been focusing on getting through the devastating end of her marriage in one piece.

Ant found fame as part of a double act with pal Dec, with the pair hosting ITV's Saturday Night Takeaway and I'm A Celebrity... Get Me Out Of Here!

In 2007 Ant and Dec signed a deal with ITV that was rumoured to be worth around £40 million that meant they would present exclusively on ITV – they recently renewed this deal for an estimated £30 million which sees the pair cemented with the channel until 2019.

Cosmopolitan claimed that for their one-month stint on I’m A Celeb, Ant and Dec receive £2.5 million each, with the pair earning £79,000 as a per day in 2016.

As well as their work on TV, the duo are both property investors too – reportedly owning properties worth around £10 million combined.
