Popular adventurer Bear Grylls revealed that he proposed to his wife Shara naked, E! News reported.

The "Running Wild" star recently sat with British television personality Piers Morgan on the "Piers Morgan's Life Stories," where he candidly looked back on his pretty wild wedding proposal.

Grylls, 40, said he popped the question while they were skinny dipping.

"I pulled out the ring from my butt cheeks," Grylls said, according to The Daily Mail. "She was standing there going, 'What are you doing?'"

The question, however, had to be repeated because Grylls said he was swept away by "a massive Atlantic roller" as he was speaking.

"I had all the seaweed and I was spinning around, so I tried it again and, and in this sort of moment of heavy sedation, she said, 'Yes,'" the British reality star said.

The couple, who tied the knot in 2000, has three sons together.

It seems that the former Special Air Service soldier is fond of taking off his clothes in the wild.

Grylls, who is also known for hosting the popular shows "Man vs. Wild" and "Get Out Alive," told Morgan how much he loves to do things, such as playing the piano and diving off cliffs, in his birth suit. In fact, the host said he accidentally sent a nude selfie to British TV presenter Dermot O'Leary while he was vacationing on his private island in North Wales.

The photo, shown on ITV's official YouTube page, shows Grylls naked and airborne while in the middle of diving upside down from a cliff into the sea.

"The thing is with this photograph, I looked at it on iPhone and when [O'Leary] texted, he said, 'Where are you?' and it looked fine," Grylls said.

The adventurer only realized later on that a part of his crotch was visible in the photograph.

"It was an incredibly cold winter's day," Grylls said.

The interview, however, was not all about Grylls' love for nakedness. The reality show host also addressed accusations that his show, which is about surviving in the wild, is staged.

Grylls said of all the accusations, the one with "substance" was the allegation about a hotel, which he admitted that he had done for a night.

"I really regret that but it's not my first mistake, it's not my last mistake and I think I had to develop fast, you know broad shoulders for this, but it was a baptism by fire into the negative media side," Grylls said, according to Mirror.
