Davina McCall, 52, showcases her enviable physique and taut abs in matching red sportswear

She is in the middle of a war of words with Big Brother’s Brian Dowling. 

But Davina McCall put it to one side as she showcased her physique in a stunning snap on Instagram on Monday.

The TV star, 52, was a vision in red as she donned matching leggings and a crop top.

She showed off her taut abs, clearly enjoying the results of her intense workout regime. 

The presenter posed in front of the mirror for the selfie and accessorised with gold bracelets and rings.

She captioned the post: ‘Lady in redddd. On QVC today talking all about my home workout fitness range … on at 1 and an hour long show at 5.’

It comes amid an ongoing row with Big Brother’s Brian Dowling as a result of its new Best Shows Ever series.

The reality star, 42, wrote on his Instagram Story on Saturday: ‘I can’t believe I’m in this position AGAIN where I’m having to justify my feelings regarding BIG BROTHER.’ 

He then posted a lengthy statement, directed toward Davina, 52, which read: ‘I’m really sad that you have again posted something today which continues to fan the flames of this on social media and in the press. 

‘On Thursday morning I posted a video on Instagram saying that I was hurt and upset that I wasn’t referenced at all as a host of Big Brother in the chat between all the presenters, and how this plays into my general treatment by the production company since they fired me. 

‘This was not a personal attack on you, Rylan or Emma at all because as far as I’m aware you do not make or edit the show and I’m a huge fan of all of you as presenters.’  

Brian was initially upset by the new Channel 4 series, which looks back at the most iconic episodes of the show, because he wasn’t noted as being a presenter. 

He presented the show from 2011 to 2013 before being taken over by Emma Willis – something he claims he wasn’t told about and only discovered after reading it in The Sun. 

During an interview with Emma, 44, Rylan Clarke-Neal asked what it was like to take over as presenter of Big Brother after working with the ‘Big Mother’ Davina, 52. 

Emma said: ‘You poo your pants a bit, you think you can never follow the Queen so just try and do as good a job as possible.’

Davina defended her statement by tweeting to say: ‘This is what he said. He was referring to when she worked with me on C4. 

‘Clear as day. He never said she took over from me as host.’

Brian’s statement continued: ‘This was me saying that my feelings were hurt, as I felt that my hosting six series of the show was airbrushed out. 

‘I understand that the Channel 5 shows were not being shown on your new series, however Emma’s role as host was specifically discussed and Rylan’s Bit On the Side show was also referenced during the series. 

‘I felt sad that I was not even referenced as the host bearing in mind there has only ever been three of us. ONLY THREE OF US.’ 

He continued: ‘This wasn’t about any references to me as a housemate at all, and I really do appreciate the lovely things that both you and Rylan said about me on Thursday night’s show. 

‘Subsequently I wasn’t going to say anything else about it. Then on Thursday night after the show aired you personally decided to tweet that I was asked to appear on the series but turned it down and tagged me in the post. 

‘Why did you feel that it was appropriate to post that? Even if you were being asked then surely you would be well aware that it would make me look bad and incite bad comments about me, when you had no idea why I might have declined to take part? 

‘Did I turn you down personally? No. 

‘Did you or anyone else ask me why I might have turned it down? No.

‘I did not turn down filming a 10-second clip as an insult to you or Rylan. I said no because it once again highlighted how I am treated by the producers of this show and it triggered lots of mental health issues for me yet again. 

‘When I was fired I was hurt, upset and publicly humiliated. My mental health and confidence has suffered terribly for the last seven years because of that and other events that occurred whilst I was the host. 

‘My career came to a halt because I could not even consider working on television for a good number of years after that and my reputation damaged. 

‘I think that is a very good reason why I did not want to film a 10-second clip, and you have no idea of what really went on seven years ago and what I went through at the time.’

He added: ‘Once I saw your tweet and the amount of vitriol and abuse I was getting in response to it, I felt I had to post something explaining why I didn’t want to film the clip. 

‘This is not something I wanted to do, but I felt I had no choice bearing in mind how much poison and criticism I was personally getting. 

‘I certainly don’t think I didn’t anything unreasonable in posting it – I had to make a comment in light of your very bold ”FYI” post to your 2.7million followers. 

‘I haven’t said anything since. However it’s now Saturday and you are still posting about this today. I genuinely don’t understand why, but I would really like to draw a line under this now please, as by continuing to post all you are doing is encouraging more negativity.’
