The loved-up couple were chatting to Made In Chelsea’s Jamie Laing on his online show In Bed With Jamie.
During a game called Shameless, Charlotte and Stephen went head to head to answer some brutally honest questions.
The blonde E4 star nonchalantly asked the hosting duo where the naughtiest place they’d had sex was.
And the Shipwrecked star had no qualms in admitting that him and Charlotte did the deed while taking a break from filming their MTV show Just Tattoo Of Us.

The former Geordie Shore babe then laughed as she nodded and said “yeah, we did”.
Charlotte, 27, then dished out some gossip from her days in the Newcastle house.
When asked if she’d ever got up to anything scandalous on a show that never made air, Charlotte recalled a house party the Geordies once held.
She explained: “There were about 60 people in this house and two toilets. The queue is so bad.

“We’re up in the room getting our pyjamas on and I had a wee in the bowl. It was the wee bowl we were all using and a bit of poo came out.
“So I’m walking through the house with a bowl of s**t and p**s and poured it down the sink.”
Bear also gushed about how he would “marry” his co-host and took the opportunity to exclusively show off his new tattoo.
The North London-born star proudly debuted his brand new ink of a C on his ring finger.

Their programme sees couples and friends put their trust in one another as they prepare to be tattooed without seeing the design first.
There are been many controversial tattoos from the show including Charlotte’s pals Sophie Kasaei and Holly Hagan kicking off over their new additions.
And Charlotte recently revealed that she’s already thinking about her dream guests for the second series.
She told The Sun Online: “It would be my absolute dream to have Little Mix on the show.
