has been rushed to hospital.
The 42-year-old singer’s wife Ariana Cooper Whibley confirmed her partner has pneumonia and that there’s ‘a possibility of heart failure’.
Model Ariana, 32, posted two photos of her husband on , one of which showed him being loaded off an ambulance.
She also penned a lengthy update about Deryck’s health and explained the situation ‘brings back a lot of really difficult memories’.
Ariana said in full: ‘Deryck and I were supposed to be in Chicago right now, celebrating our eight-year wedding anniversary but the universe had a different plan for us.
‘We spent the entire night in the ER and will now be spending the next few days here in the hospital as he fights through pneumonia.
‘The scariest part is that there is a lot of strain on his heart and they are telling us that there is a possibility of heart failure.’
She went on: ‘This is obviously not our first time in a situation like this but it brings back a lot of really difficult memories seeing him back in a hospital bed connected to wires and IVs.
‘I know how strong he is because I have witnessed what he has been able to overcome but that doesn’t make it any easier to see. I’ll do my best to keep everyone updated but if you could keep him in your heart over the next few days, we could really use it.’
Deryck has been sober since 2014 after he collapsed in his kitchen and was rushed to hospital, where doctors said his liver and kidneys had failed.
Speaking after that health scare, Deryck previously told Vice: ‘It was the right time in my life for it to happen. I’m glad it happened now and not when I’m like, 50, because my body wouldn’t have been able to handle it. But it’s unfortunate that it had to even come to that.
‘However, now I’m feeling better than I’ve ever felt. I’m healthier. I’m in the best shape of my life.’
Ariana – who has son Lydon Idby, three, and daughter Quentin Arlo, six months with Deryck – previously suffered with depression and survived a suicide attempt in 2013.
