Kate Winslet refused to let the director of 'Mare of Easttown' cut "a bulgy bit of belly" from her sex scene.

The 45-year-old actress - who stars as detective sergeant Mare Sheehan in the hit US crime drama - has revealed she wouldn't allow her appearance to be edited on the show and on any promotional content.

Kate wanted her character to look like a real middle-aged woman because there are already too many filtered and edited images out in the world.

She explained: "Listen, I hope that in playing Mare [Sheehan] as a middle-aged woman — I will be 46 in October — I guess that's why people have connected with this character in the way that they have done because there are clearly no filters.

"She's a fully functioning, flawed woman with a body and a face that moves in a way that is synonymous with her age and her life and where she comes from. I think we're starved of that a bit."

The 'Titanic' star - who filmed one of the most famous steamy sex scenes of all time in the back of a car with Leonardo DiCaprio in the 1997 disaster movie - knew a promo shot for the series had been edited immediately, because she knows "how many lines I have by the side of my eye".

And when director Craig Zobel told her he was going to edit the belly area, she responded: "Don't you dare!"

The Oscar-winner also admitted this could be her last nude scene - but not because of her age.

She added to the New York Times: "I think my days are getting a little bit numbered of doing nudity.

"I'm just not that comfortable doing it anymore. It's not even really an age thing, actually. There comes a point where people are going to go, 'Oh, here she goes again.'"

Meanwhile, Kate previously admitted she was "by far the least self-conscious" she's ever been filming a sex scene with Saoirse Ronan in 'Ammonite'

The screen star revealed she and the 27-year-old 'Little Women' star were fully in charge of their lesbian romp and it's the one she's most "proudest" of.

She said: "Saoirse and I choreographed the scene ourselves.

"It's definitely not like eating a sandwich. I just think Saoirse and I, we just felt really safe. Francis (Lee, the director) was naturally very nervous. And I just said to him, 'Listen, let us work it out.' And we did. 'We'll start here. We'll do this with the kissing, boobs, you go down there, then you do this, then you climb up here.'

"I mean, we marked out the beats of the scene so that we were anchored in something that just supported the narrative. I felt the proudest I've ever felt doing a love scene on 'Ammonite'. And I felt by far the least self-conscious."
