Nick Jonas has taken his purity ring off forever.

He said: "I'm comfortable enough to talk about sex and other things in a way that is transparent and, I think, more relatable - because this is who I am as a man. It's a very strange thing when I look back. There are times I'm surprised I didn't lose my mind. But it was part of my journey and me trying to do the right thing."

Nick is currently dating Olivia Culpo, who was named Miss World in 2012, and admits it's "cool" being the envy of men around the globe.

He told The Sun newspaper: "It is cool, I can't deny it! It is fascinating to me at times. I still geek out about it. But I don't think it defines our relationship."

Nick, who met Olivia at a New York Fashion Week party in 2012, explained his new single 'Jealous' is about the attention the 22-year-old beauty gets from other men.

He said: "The song came about nine months into our relationship. Someone kept staring at her and it was kind of uncomfortable because we were clearly on a date. It was such a disrespectful situation.

"We were at the beginning of our relationship, so I would have those moments of feeling nervous and jealous.

"The song is a topic many men are afraid to talk about. It's vulnerable and it's a weird position to be in. But instead of getting frustrated, I went to the studio and wrote the song the next day."
