Dancing on Ice's Stephen Mulhern left co-host Holly Willoughby speechless with a very racy quip during Sunday's live show. 

The ex This Morning star's mouth fell open in horror when her pal pretended to miss hear after she revealed contestant Chris Taylor was dancing to the song 'Golden Hour'.

Stephen, 47, acted shocked by the revelation, jokingly thinking that Holly, 43, had been referencing an X-rated sex act. 

Stunned Holly gasped when it dawned on her, before the camera cut away to see the Love Island star and his partner rehearsing before they took to the ice. 

It comes after EastEnders actor Charlie Brooks, 43, was left without a partner after their professional dancer Eric Radford had to pull out due to an injury.

Announcing the news, Dancing On Ice's official X account revealed that he sustained his injury during rehearsals. 

Alongside a picture of the pro skater, the account penned: 'Unfortunately, Eric Radford has sustained an injury during rehearsals.

'Following medical advice, he will not be able to skate with Charlie Brooks this week. Brendyn Hatfield will skate with Charlie.

'We wish Eric a quick recovery and hope to see him back on the ice next week.' 

It believed that Eric sustained a back injury and was rushed to the hospital for an MRI scan. 

Speaking about the shock injury, Charlie told the Sun: 'Eric had an injury in his back and then his quad wasn't firing properly so he's having to have an MRI and has been told he has to have this week off the ice, which is so gutting.

'It's such a shame, he's my number one and I will be lost without him.

'But I'm trying to flip it and think that it will be exciting to be able to skate with someone else, and Brendyn is wicked so it will be nice to get to know him a little bit.'

And Eric is not the only professional who has had to pull out of the show during this season as Christ Tayor's partner Vanessa Bauer has withdrawn from the competition after tearing ligaments in her leg while rehearsing for last Sunday's show. 

With the German skater absent, Chris was hastily partnered with Robin Johnstone for his latest ice routine, performed to the Pokémon Theme on February 2. 

But the performance was overshadowed after the new partnership lost their footing and tumbled onto the ice before regaining their composure and completing the routine. 

Sharing the news of her injury in an Instagram video, Vanessa said: 'I'm here today with rather upsetting news. I am unfortunately not going to be able to continue on Dancing on Ice with Chris. 

'That's really upsetting for me. I have trained Chris since October last year and it is always such an amazing achievement for myself to see someone else progress so much in a skill they've never done before. 

'So it's been really rewarding for me to watch this whole journey for Chris [and] the way he's got better week since October and also since the live shows started.'

She added: 'I unfortunately had a little accident backstage last week on Dancing on Ice just before the live show on Sunday.

'And I didn't realise how bad it was then, but we did an MRI and it turned out that I have a completely torn ligament, grade three sprain injury and a major grade two sprain injury.

'I shouldn't be skating on an injury like that and so I'm taking all of the advice from the medical professionals here, I am in very good hands.'

Revealing she would be undergoing rehab for her injury, Vanessa added: 'My pain threshold, I don't trust it, I have been skating this whole week with a lot of pain but I just didn't realise that it was such a significant injury so I didn't voice my pain. 

'It just goes to show that you should listen to your body and try to tune into your body a lot.

'I don't want this injury that is already bad to get even worse and so the one sensible decision is to step away, do rehab, focus on my health - I guess mental health as well - because it's really bad that I have to leave.

'But I'm excited to get better and to get back to skating properly every single day.'
