Nick Jonas may have had the intention to withhold from sex until marriage when he was a kid in the Jonas Brothers, but that goal certainly didn't stick.

The 22-year-old singer/actor admitted to Wendy Williams on her Wednesday show that he's not a virgin, despite he and his brothers wearing purity rings at the start of their careers and vowing to not have premarital sex.

"I don't regret it," he says of the sex pledge he took. "I think it was an important part of my childhood and it was that. As I grew up, I sort of figured out what was important to me and my own belief system. We all grow up and we all live life and find out what’s important to us, that’s what happened. I went on that journey myself and I’m now comfortable with who I am and what I believe in and I’m an adult."

When the outspoken host asks him point blank if he's still a virgin, a blushing Nick confesses, "No. As I said, I'm an adult in all ways."

This sex confession comes after Nick filmed a graphic, NSFW sex scene for his TV show "The Kingdom." "Another little thing is my character has a big storyline revolving around his sexuality," he recently told Andy Cohen on "Watch What Happens Live."

Nick is currently dating Miss Universe Olivia Culpo, and tells Wendy Williams that they're both "enjoying the ride." He also admits that his new song "Jealous" is about the beauty queen. "We went out one night and this guy was looking at her for a little too long," he recalls. "It was uncomfortable. I'm not a jealous person and this was an experience that I was one or two drinks in. I really got into it and then I decided to let me just process this a different way and go into the studio and write this song."

Nick isn't the only JoBro to admit to not keeping his virginity pact. His older brother Joe, 24, confessed to New York Magazine this past December that he had sex at age 20. "I did other stuff before then, but I was sexually active at 20," Joe disclosed. "I'm glad I waited for the right person."
