Tom Grennan was left covered in poo when he smashed his car into a London hotel's sewage pipes in an underground car park

Tom - who was wearing a white suit - recalled how the G-Wagon's sun roof "ripped open" before his vision went "dark" and he felt cold all over his body. Then he realised he and his car were "covered" in human excrement and other waste.

Tom - who gets "PTSD" from recalling the stinker of an ordeal - told Roman Kemp on the 'You About?' podcast: "Everything went dark, right? And, and cold. And I'm sat in this brand-new G-Wagon with human waste.

"There's tampons in the car. There's like - I've got a white suit on because I'm going to the ballet, so I wore a white suit to the ballet. So now I'm like covered in waste.

"And, honestly, I had to do the whole journey again because I had to turn the car around.

"There's full-on solid poos. And I'm like, Oh my days."

Tom, who cried as the G-Wagon's sunroof caved in, bawled when he phoned Danniella to explain what had happened and to apologise for being "late".

And the 'Let's Go Home Together' singer, who did not want to go to the ballet in the first place, was shocked by Danniella's response to the dirty disaster.

Tom said: "I got up and rang my missus because I was late, and I was like in tears.

"And I rang my missus like, 'Well, you're never gonna believe what's happened.' And she went, 'I knew you didn't want to go to the ballet!"

"I couldn't believe her reaction!"

Before telling Roman - whose dad is former Spandau Ballet bassist Martin Kemp and mum is ex-Wham! vocalist Shirlie Kemp - about his tale, Tom said: "This car story gives me PTSD. Like, I can't go into underground car parks."
