Kate Beckinsale posed on top of a bin in a quirky photoshoot after slamming 'a**hole' followers who criticised her weight. 

The British actress, 51, wore a pair of her signature towering platform heels, with stacked soles, silver glitter and a lace-up design. 

Kate, who recently revealed her weight loss is down to 'stress and grief', wore a pale blue satin shirt and white skinny jeans. 

She pulled her hair back into a glamorous piny tail and accessorised her outfit with a pair of huge sunglasses.  

After standing on top of the public bin, Kate later perched on the edge for another snap, which she shared to Instagram.

She captioned the post: 'À la poubelle,' meaning 'in the bin' in French. 

Kate has caused concern on social media over several unexplained health scares over the last year, including spending weeks in the hospital and dropping so many pounds that fans called her 'too thin.' 

This week she revealed her weight loss is down to the 'stress and grief' of the death of her stepfather and her mother's cancer diagnosis as she hit back at trolls.

The actress slammed some of her 'a**hole' followers, who told her she needed to put on weight in the comments section of an Instagram post.

After sharing a video clip in a crop top and bikini bottoms, one follower queried where her 'a**' had gone and encouraged Kate to 'do some squats'.

Another claimed her body had 'shrank' while another insisted that she 'seemed upset' in the video posted on Monday evening. 

However, Kate fired back at the cruel comments ands explained that there were several reasons for her changed figure, including a six-week hospital stint. 

She replied: 'No, actually, I watched my stepfather die quite shockingly, my mother has stage 4 cancer and I lost a lot of eight from stress and grief...

Kate's stepdad Roy Battersby died in January following a 'brief illness' after being diagnosed with two forms of cancer the summer before (pictured left with her mother Judy right)

'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***ing a**. I suggest shoving something up it, like a large pineapple or a brick.'

Kate's stepdad Roy Battersby died in January after suffering 'a massive stroke' while battling two forms of cancer, which he was diagnosed with the summer before.

Shortly after his death, Kate also revealed that her mother Judy Loe had also been told she has stage four cancer.

In March Kate revealed she had been hospitalised after sparking concern among her fans with tearful selfies.

She later explained the reason behind her hospital stint in a now-deleted Instagram post, writing: 'I spent six weeks in hospital due to copiously vomiting blood from a Mallory Weiss tear caused by the stress of a whole year ripping a hole between my oesophagus [sic] and stomach.'

'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.'

In recent months, Kate had been caring for her mother and late stepmother after flying them out from the UK to stay with her in Los Angeles.

'Kate has been caring for her parents, who both have serious illnesses, for most of the year,' a source exclusively revealed to DailyMail.com late last year. 'She brought them to her home in LA and has made looking after them her number one priority.'

On January 10, Kate announced the death of stepfather Roy aged 87.

The insider revealed that the actress — whose biological father Richard Beckinsale died in 1979 at 31 from a heart attack in his sleep — has been feeling the emotional toll in recent months.

'She was spotted this week several times crying in the corridors of UCLA hospital,' the source added. 'Her friends are very concerned that she has been under relentless strain for months and hardly sleeping or eating.

'Kate appears to be very strong but this has been incredibly hard and, given that she lost her father so young, is affecting her very deeply. Her friends are concerned for her own health.'

A second source explained that her mother Judy has chosen to keep her health battle private, stating: 'She's extraordinary, you wouldn't even know by looking at her. She has been keeping a very positive attitude throughout everything.'

Kate shared a picture of Roy's order of service that revealed he was cremated on Monday February 19 at Mortlake Crematorium near Kew in west London.

Another person asked: 'How's your health Katie? You look like you have lost some weight?', to which she responded: 'It's great now thanks'

At the time, Kate did not reveal why she was in hospital  

Last month, Kate shared a picture of Roy's order of service that revealed he was cremated on Monday February 19 at Mortlake Crematorium near Kew in west London 

Kate's mother Judy married Roy 18 years after Kate's father, Porridge star Richard Beckinsale, died.

Roy enjoyed his own successful career as a director, working on major British on-screen hits including Inspector Morse and Cracker. His most recent directorial credit was for a 2006 episode of A Touch Of Frost.

Kate's biological father Richard Beckinsale was best known for his roles as Lennie Godber in the BBC sitcom Porridge and Alan Moore in the ITV sitcom Rising Damp.

He also had a daughter — Samantha, 55 — who is his only child from his marriage to Margaret Bradley.
