Joe Jonas was caught watching porn when he was younger

He said: "I would use my address to log into the websites, and I did this for seven days straight.

"A month later - and by the way, my dad was a pastor at the time - for a week or two straight there was a postcard with a naked woman on it saying 'Come join us again Joe' or 'We really miss you' or 'You naughty boy, come visit us again.'"

And the 27-year-old singer - who grew up as part of the Jonas Brothers - admits it was tough growing up in the spotlight.

He added: "I wouldn't wish it on anybody. [But] it moulded me to where I am today. At the same time, it's tough to say that it's a bad thing because I feel pretty open, and there's not much I won't talk about [now] you know.

"There is a lot of obsession over secrecy in this day and age, and you're kid living in a grown up's world. I definitely feel for a lot of young artists going through a lot of similar things."

Joe is now making waves as part of pop rock band DNCE and admits he was thrilled when their song 'Cake By The Ocean' flew to the top of the charts.

Speaking to the new issue of Notion magazine, he said: "I look at the song like this big leap of faith that I did on my own. And whether it was with my brothers or whether it was with two other guys randomly in the world, it's the first time for me that I did something on my own in a way where you pat yourself on your back like 'I did it, I can do it.'

DNCE's new single 'Body Moves' is out now and their hotly-anticipated self-titled debut album can be pre-ordered now ahead of its November 18 release.
