Annie Kilner's sister has branded Lauryn Goodman 'evil and cruel' following the model's fling with Kyle Walker.
Walker has known Annie since they were 17, with the couple having three children together - with a fourth on the way.
However, the couple recently split with Annie taking to social media to confirm the news.
It has since transpired that Walker has actually fathered two children with Lauryn, instead of just one as was previously believed.

The City star, who starred as Pep Guardiola's side won a historic treble last term, has apologised for his behaviour.
And Annie's sister, Sian, has now taken to social media to condemn Lauryn - dubbing the influencer 'evil' and 'cruel'.
“When does your torment end? My sister, who is now seven months pregnant, has faced your cruelty for almost five years now. What's your goal?" she said.
“To see how much stress you can put on a pregnant woman? To create a false victim narrative around what you did?
“You clearly lack empathy but this level of evil is out of control and harms everyone - especially the children.
"Stop accusing others; your true self is revealed.
"The so-called 'loving relationship' is a facade.
"It's not fooling anyone so why don't you just give us all a break and stop.
“Also, He has one sugar, Nestle Coffee Mate and semi-skimmed milk. But that's the coffee you get at home.. not the ones in hotels or air b&bs.”
Walker, earlier in the week, said he never had a relationship with Lauryn - something the model disputes.
"That is something Lauryn could never say," the City star told The Sun.
"We've never been out for food, we've never been to the cinema.
"I admit Lauryn was a friend for a long time. I probably met her back when I was 20, 21. We then have our episode in 2020.
"I'm 33 now, that's a good nine years before there has been anything of the sort.
"After that there was nothing of the sort.

"To have a relationship with someone....Would she even know how many sugars I have in my coffee, if I have sugars? She couldn't tell you."
Walker also admitted that he considered moving to Bayern Munich in July while the scandal was going on.
“I tried to escape. Did I want to leave City? No, of course I didn’t. We’re the best team in the world at the minute," he said.
“But it was a chance to get away from England and the media I was going to get.
“I was aware the clock was ticking. I came very close to moving. We were having conversations.

“If I’m in Germany and this happens, Annie leaves and I’m now in Germany on my own.
“My kids wouldn’t be around the corner where I can see them. There’s pain and emotion at the moment but I can go to the house, take the kids to school, and my little lad to football.”
Lauryn has seemingly accused Walker of being a 'pathological narcissist'.
The City star is expected to feature when his side face Burnley on Wednesday night (7.30pm).
