Ant McPartlin and Lisa Armstrong's strained marriage has come under intense media scrutiny in the past few weeks. As reports about the couple's split start to surface, it is believed that the TV presenter could end up paying up to £15m in a divorce settlement.

McPartlin, fresh from his successful stint as the I'm A Celebrity host alongside regular partner Declan Donnelly, is said to be worth £30m.

According to divorce lawyer Cara Nuttall who spoke to the Mirror: "The starting point will always be a 50:50 division of all assets.

"It is likely her lawyers will argue that due to the length of their relationship there is no room for negotiation on that."

The 42-year-old has been married to make-up artist Armstrong, 41, for 11 years. But after McPartlin checked into rehab for prescription drugs addiction earlier this year, their relationship began to suffer.

The pair have been living separately for months and Armstrong has allegedly confided to friends that their marriage is "definitely over".

An insider told the Sun: "Ant's rented flat was meant to be a temporary arrangement but there are no signs of him moving.

"It's becoming harder to see a way back. He knows they need heart-to-heart talks but since he has returned from the jungle they just haven't happened. And what's more, it doesn't look likely to any time soon."

The source also claimed that Armstrong was looking to set up meetings with lawyers to finalise a divorce suit.

"She has told several friends their marriage is definitely over and that she is considering meeting lawyers to discuss things. But on other days, she has been more confident they can fix things.

"She desperately wants it to work out," the source was reported saying.
