Wrestler-turned-actor Dwayne Johnson no longer bothers trying to fit into a crowd because fans recognise his towering, muscular physique wherever he is in the world.

The Jumanji: Welcome to the Jungle star recently took to Instagram to poke fun at how much he stood out during his Skyscraper promotional tour in China, where he turned heads in Beijing and Hong Kong as he walked down the street in his gym gear.

"Always fun blending in everywhere I go," he captioned the funny snaps.

Dwayne admits he now accepts people will stop and stare at him.

"It's not that I find it hard to fit in, it's just that I literally do not fit in!" he laughed.

"I'm trying to walk down the streets, and I kind of stick out a little bit," he recalled of his trip to China, before quipping, "I think it's the bag I'm carrying; I'm not too sure what it is!"

Dwayne, 46, has long given up attempting to disguise his identity in public, but insists he wouldn't have it any other way, because he remembers how tough life was financially when he was a nobody.

"It was, I think, when I was about 22, 23...," he told breakfast show Good Morning America when asked about the last time he was able to go out unrecognised. "But I always tell people, the alternative to that is I go back to nobody knowing who I was, or getting evicted when I was 15, couldn't afford to pay the rent, so you get no complaints out of me."

"And plus, I stopped trying to fit in," he added. "Usually, when I tried to fit in, I used to just wear a goofy hat, and it was like, 'Oh, there's The Rock with a stupid hat...'"

Dwayne has frequently recalled the poverty he faced before rising to fame in the wrestling ring in the mid-1990s, and even named his entertainment firm Seven Bucks Productions as a permanent reminder of the little money he had before scoring his big break.
