Hugh Jackman has revealed he was left a little red-faced recently - when he mistakenly thought he was meant to go naked at a spa in Japan. Scroll down for video.
The Wolverine star thought he could let it all hang out as he enjoyed a beer at some hot springs at Mount Fuji.
According to the Metro, he said: "The place is separated male and female and they hand you a towel, a small washcloth and there are eight different types of tubs with heats of different temperatures.
"I'm getting so hot and I'm using the towel they gave me to dip into the cold water and put it on my head and I was getting very strange looks from everybody."
He even thought at one point that the looks were because he was the only white person there. But a helpful fellow spa-goer pointed out the error of his ways.
According to the Daily Mail, Hugh added: "I was feeling uncomfortable and finally this guy in the tub grunts and points to my head and then grunts and points to my private parts.
"Finally I realised the towel was meant to be covering my privates and I'd spent about an hour just waltzing around this place with this thing in one hand and a beer in my other hand!"
Cringe. But we're sure the ladies didn't really mind too much.
