Kate Beckinsale has slammed an "a***hole" troll who mocked her figure as she grieves the loss of her stepfather

In response, Kate reminded the individual that she is currently mourning the loss of her stepfather Roy Battersby, her mother is battling cancer, and she herself recently had a stint in hospital for a torn esophagus, a flare-up from mast cell disease, and had to face "reactivated PTSD" stemming from the death of her dad Richard Beckinsale when she was a child.

As a result, Kate found it difficult to eat.

She fumed back: "No, actually, I watched my stepfather die quite shockingly, my mother has stage 4 cancer and I lost a lot of weight from stress and grief...

"Quite quickly and then I was in hospital for six weeks because the grief had burned a hole in my oesophagus, which made me vomit copious amounts of blood, and I found eating very hard...

"And I just worked very very hard on a movie that was actually quite triggering because it also involved the theme of the death of my father so I'm not really concerned about what you think about my a**. Maybe you should worry about your own f****** a**. I suggest shoving something up it, like a large pineapple or a brick."

Kate recently flashed her bare buttocks at a department store to help deal with the death of her cat Clive.

The 'Jolt' star lost her beloved pet and received some "horrific news", so she decided to "moon" London store Harvey Nichols to try and raise her spirits.

Revealing a cheeky video of the moment she pressed her backside against a window, she wrote on Instagram: "The day after Clive died and I received some of the most horrific news I've ever received that next morning...

"Sometimes there's nothing for it but for your friend to show up as hard as possible and spend the evening making prank calls and mooning Harvey Nichols because sometimes when the bottom falls out of your world the only response after crying till you're sick is your own bottom

"@nina_kate I'll never forget you jumping into the fire with me x (sic)"

Kate recently admitted she's just been "trying to survive" her year from hell.

In May, a troll commented on the actress' weight in pictures from a trailer on a movie set, prompting her to respond: "I nursed my [step-dad] to his death early this year. My mum also has stuff going on. I am adjusting to watching two fathers die, one when I was 5, one in January of this year."

She added that she "experienced a severe flare of mast cell disease ... [caused] by stress, shock and grief ... That's what I am prepared to disclose that has contributed to some weight loss.

"What you think of my appearance and how I should look, independently of any circumstances in my life and my family's is not important.

"I am trying to survive what feel like unbearable losses, reactivated PTSD from discovering my very young father's almost dead

body as a very young child alone in the night, and working to support the family I have left."
