Rylan Clark-Neal has recalled an intimate moment he once had in the 'Big Brother' toilets, when Claire Richards was keeping guard at the bathroom door.
The 31-year-old star - who won the celebrity edition of the Channel 5 reality show in 2013 and went on to host the 'Bit On The Side' spin-off until 2018 - revealed he had some alone time to pleasure himself on the programme, while the Steps singer kept a lookout to make sure no one caught him.
Speaking on Channel 4's 'Big Brother: Best Shows Ever', he said: "Listen. When I was in there I had to.
"Did it in the bathroom, Claire from Steps sat outside. She was on watch!
"Boy's got to do what a boy's got to do."
Rylan made his confession after he and co-host Davina McCall chatted about 'Big Brother' series six, when housemates - including Kemal Shahin, Science, Kaosi Musambasi and Sam Heuston - had to sit in a cardboard box for as long as they could.
Sam appeared to be having some fun solo time in her box, and Davina was shocked as they reflected on the outrageous moment.
She laughed: "Can we discuss this? Because I completely forgot about this until I watched this episode, that Sam was having a good time in her box.
"There were noises and then a couple of the guys looked in the box and were like, 'Oh my gosh how could you?' "
Rylan teased: "Do you not spend that time when you're in a cardboard box in the middle of a house all alone?"
Davina quickly fired back, and insisted Sam should have simply been a bit quieter.
She added: "Not when someone could look in. If you're going to do it and wear a microphone, could you please try and just be a bit more subtle and quiet about it.
"Less of the moany groanies."
