Mum-of-four Annie Kilner, 31, wants around half of the Manchester City star's £27million fortune to fix their relationship after he fathered two kids with Lauryn Goodman.

Kyle Walker's furious wife Annie Kilner has demanded £15million cash to save their marriage

She is understood to have obtained preliminary legal advice ahead of any split that would see her net half of Manchester City defender Kyle's fortune.

The £150,000-a-week ace, 34, played in their 1-1 draw with Newcastle United at the weekend — but off the pitch his personal life continues to backfire.

Tensions are said to have risen recently after Annie's sister Sian gave birth to a son after a fling with a married man.

It mirrors Kyle's torrid situation with influencer Lauryn, who had two children with him while he was with Annie.

A source told The Sun: "It's a s***show at the moment.

"Kyle and Annie are arguing about pretty much everything.

"She's told him she will only consider giving it another go if he gives her half of his money first.

"She's been told she's entitled to half of his wealth if they split — and doesn't want another penny of her share going to Lauryn.

"She wants the independence and security divorce would bring her, but wants to try and keep her family together at the same time.

"Annie and Kyle have spoken with solicitors about making this financial arrangement happen.

"He is happy for her to have the money as he wants security for them — regardless of how their relationship ends up.

"Kyle wants financial security for Annie and his boys.

"Their relationship changes from week to week, but at the moment she can't see a way of saving the marriage and has said she is considering filing for divorce.

"It has been a really tough time for Annie."

Sources say revelations about Sian have created tensions between both families.

Another said: "Sian gave it to Kyle with two barrels over everything with Lauryn but now it seems it is a case of the pot calling the kettle black.

"Kyle is throwing Sian's behaviour back in Annie's face every time there's an ­argument and using it as an excuse to make his behaviour acceptable.

"He is saying that Annie can't have a go at him when Sian has done a very similar thing — basically acting as if it is the norm.

"Sian has always had a go at him about what he has done to her big sister — now she has done the same with another man.

"Sian doing this is just an extra layer to the mess that Annie doesn't need."

Lauryn, 33, became pregnant while Kyle was on a break from Annie in 2019.

Their son Kairo was born in April 2020. Kyle and Annie then rekindled their relationship and got married in 2021.

But a year later he reconnected with Lauryn and she gave birth to their second child — daughter Kinara — in August 2023.

Annie learned the truth in a text from Lauryn last December.

A source said: "They had an emotional phone call.

"They both apologised to each other — Annie for revealing the gender of Lauryn's child which had devastated her."

Annie, who was pregnant with her and Kyle's fourth child at the time, was left reeling and announced their split two weeks later.

This April she gave birth to her and Kyle's son Rezon.

The family holidayed in Turkey this summer.

Pals said Annie is still weighing up her options and, while Kyle was in and out of the family home, she wanted him in their sons' lives.

A source said: "Annie is insisting to friends they are not back together and just trying to navigate a way forward.

"All she really cares about is the kids and will do all she can to protect them."

Kyle spoke to The Sun in January of his regret over cheating on Annie.

He said he wanted to repair the relationship but admitted he had broken Annie's heart. Kyle said: "I'm sorry I've had a second child with Lauryn and hurt my best friend. It's horrible to say that out loud. I've hurt someone I truly believe is my soulmate."

In June and July, Annie travelled to the Euros in Germany with their sons, but the couple appeared worlds apart in pictures.

Less than 48 hours after England's final defeat to Spain, Kyle was in court to thrash out a financial settlement with Lauryn.

A judge later accused Lauryn of using him like "an open-ended cheque book".
