Alison Hammond launched a blistering attack on her 'rubbish' This Morning dress - insisting that 'it stinks' and she's 'donating it to charity' after getting a nasty shock on the ITV set.

The host, 50, was joined in the studio by fellow presenter Dermot O'Leary, 52, on Friday, where they began by discussing Trump's recent visit to the UK and discrimination against pregnant workers.

But talk soon turned to Alison's deep purple belted leather dress when presenter Jeff Brazier complimented her outfit choice.

However Alison herself seemed to have been unimpressed with her look, saying of the material: 'I thought it was leather but it smells weird - I think it's PVC.

'It's something rubbish,' she continued. 'Don't worry, I'm going to donate it to charity afterwards.'

Elsewhere on the programme, she took yet another swipe at her own outfit when the hosts resumed after a break by dancing to music blaring in the studio.

Bouncing jovially, Alison said: 'I don't know what it is about this dress but it's making me dance like a granny!'

Alluding to an earlier conversation, Dermot replied: 'Well, I told you, we can't get rid of the dress.'

Fans of the show also noticed Alison's outfit, and took to social media to swap notes.

'Is it national Wear A Binbag To Work day?' asked one commenter, while another wrote: 'Alison is wearing a garden waste bag.'

'Thought I'd seen it before,' joked another, sharing an image of a sofa. Another agreed, saying: 'Alison is wearing an original DFS.'

The faux pas comes hot on the heels of a series of gorgeous selfies shared by Alison, where the TV personality showed off her incredible 11 stone weight-loss.

The host flashed a smile after undergoing a dazzling makeover by her 'glam man' Mikey Phillips in the snaps shared to his Instagram.

She wore a white T-shirt with a colourful A-line skirt and a denim jacket layered over the top.

Alison has lost 11 stone in recent years, prompted by the discovery that she was pre-diabetic – a situation she has reversed with healthier food choices and workouts.

In a recent interview with Daily Mail, she discussed how she stays trim while surrounded by cakes on The Great British Bake Off.

She said: 'I eat a bit of Paul and Prue's after they've finished judging. I only try the ones that got a handshake from Paul or ones that won. If the judges aren't impressed, I'm not trying it.'

Alison revealed how she managed to lose the pounds without the assistance of weight-loss jabs, giving an insight into her exercise plan with her personal trainer.

The TV personality, who weighed 28-stone at her heaviest, told Heat: 'I've got a personal trainer - she's amazing, she trains me when I can train.

'If I'm working, I don't train, I'll go for a walk.

'But when I'm at home, I'll go and have a session with her in the morning, just an hour. It might be four days a week.'

She also revealed her approach to her diet, saying she hasn't cut anything out completely but focuses on 'moderation'.

'I don't deny myself anything, I eat everything, but in moderation,' she added.

This Morning airs weekdays on ITV1 from 10am and is available to stream on ITVX.
