Rylan Clarkhas shared that he and Rob Rinderhave seen each other with no clothes on, though the duo joked that any romantic involvement between them would "feel like incest".
The TV stars have found themselves at the centre of dating speculation due to their tight-knit friendship and the bond between them during their adventures in Italy on their BBC travel programme, Rob and Rylan's Grand Tour.
Rylan, 36, has now tackled the rumours in a chat with Radio Times, stating: "Everyone thinks we're together because we're doing this show and we show each other affection."
He continued: "I think people still presume that two gay guys who get on must be together; that two gay men can't just be mates."

The This Morning presenter also joked that whilst he and Rob share a close bond, a romance between the duo wouldn't work, reports the Manchester Evening News.
"I love him," he remarked about his co-presenter.
"But if we were in a relationship I'd be in prison because I would have smothered him with a pillow by now. That's what marriage is, isn't it? Row all the time and don't have sex."
"Rob's seen me naked, I've seen Rob naked, that's how close we are," he revealed. "But nothing's gone in anything. "No way!" responded Rob.
The pair joined forces last year for Grand Tour, which featured them soaking up the scenery as they journeyed across Italy.
The programme proved to be a massive hit with audiences and is making a comeback for another series, with Rylan and Rob, 47, setting off to India this time around.

The BBC recently teased the show on Instagram, stating: "Following their Bafta-winning Grand Tour of Italy, Rob Rinder and Rylan are taking things to the next level and heading out of art galleries and into the teeming streets of one of the world's oldest and greatest civilisations: India.
"But can the art and culture of India help them to lead better lives?"
