How did he get so HOT? From squeaky clean singer to muscle-bound sex symbol, Nick Jonas's incredible transformation revealed

  • Found fame in 2006 with pop band The Jonas Brothers with his siblings
  • Publicly declared he would remain a virgin until marriage    
  • Has a ripped physique and recently confessed to being 'adult in all ways'

He was a squeaky clean Disney star who came to fame singing pop songs with his brothers but ten years after he shot to fame, Nick Jonas has become almost unrecognisable.

Packed with muscle, his hair cut short and a manly glower on his handsome features - the 22-year-old is doing is best to leave his years as a Christian pin-up far behind as he unveils his new ripped body and reveals he has, finally, lost his virginity.

And while his ex-girlfriend Miley Cyrus has embraced adulthood in a flurry of twerking and risque Instragram pictures, Nick, 22, is doing his best to get his female fans hot under the collar as his transformation from curly-haired child star to tough sex symbol appears to be complete.

His current solo tour in which he's discussed how he lost his virginity, and his fans having sex to his music, is a far cry from his career's innocent beginnings on Broadway, at the age of seven.

Discovered by a talent scout in a barber's shop, the youngster went on to star in a number of hit musicals including A Christmas Carol, Annie and Les Miserables, before being snapped up by Columbia Records along with his brothers Kevin and Joe aged 13.  

The trio called themselves The Jonas Brothers and branded themselves as an American pop-rock group.  

Nick and his siblings quickly gathered a strong young female following thanks to countless appearances on the Disney channel and in tweenybopper shows such as Camp Rock. 

The Jonas Brothers were also a hit with parents thanks to their butter-wouldn't-melt image and strong religious views. 

Not only did the boys promise not to drink, smoke or swear but they also vowed not to have premarital sex - each wearing a silver ring to show their commitment.

As the Jonas Brothers became hugely popular in the US, clean-cut Nick and fellow Disney star Miley Cyrus - then a family-friendly, long-haired actress in Hannah Montana - dated and she later described him as her '24/7' but despite being in love she said they argued a lot.

After their split in 2008, the young star was linked to a bevy of beautiful women including Selena Gomez, Samantha Barks, Delta Goodrem and Ashley Greene.

But after being nominated for a Grammy Award and selling over 17 million albums worldwide, in 2013 The Jonas Brothers decided to break up.

This is when Nick's image began to shift and he started focusing on his acting ambitions. 

While his ex Miley explored her coming of age with increasingly outrageous stunts from her twerking escapades to flashing the flesh on social media, Nick - who was nicknamed 'the president' for his preternatural maturity as a teenager - began some adult experimentation of her own.

In 2013 he began dating Miss Universe Olivia Culpo who he met while co-hosting the Miss USA pageant.

They made their public debut as a couple in September that year at the US Open and have been together ever since.  

Nick went on to shock fans last year after announcing on American television that he was now 'adult in all ways', implying that he was no longer a virgin. 

He also decided to remove his purity ring, telling HuffPost Live: 'This is a real growth in me and not something I'm doing any more.'

However, he was keen to reassure the world that his beliefs still stand: 'I've got my set of values, things that are important to me now at this point in my life and that's all that matters.

Despite his new look Nick say his 'belief in God is still very strong and important to me' 

'I've had an incredibly intense journey with faith and religion and my own growth,' he added.

'My belief in God is still very strong and important to me as a person and I think that's all that should matter.

'I grew up in a church environment and still have love for the church.'

With no plans to revive The Jonas' Brothers yet, Nick is busy promoting his second solo album and building an acting career. 

And with branching out on to the screen, comes a brand new look for the New Jersey-raised star.

He revealed last autumn what it took to achieve his new honed ripped physique to play a martial arts fighter whose talents lie in 'wrestling and grappling' in the TV drama, Kingdom.

Nick told Details how he overhauled his diet thanks to a food-delivery service which sent him three meals a day, plus snacks. 

He said: 'I went from consuming about 3,000 calories a day to 4,200,' adding that as he has type 1 diabetes he has always had to watch his diet.

'I have been conscientious about food for a long time. I do have guilty pleasures, though,' he confessed. 'I wasn't drinking at all while I was training for the show, but now that we're done, I keep it classy with Coors Light.'

He also added 'hardcore' workouts with trainer Gregg Miele in LA, describing his body as 'pretty Hulk-ish'.

For his new role, Nick had to completely transform his body: 'I had about six weeks to put on 12 to 15 pounds of muscle before filming started'

Since going on tour to promote his new album - and recently getting UK women hot under the collar as he promoted his new single on this side of the pond - it's clear we may be seeing a lot more of his new sculpted physique.

As well as fighting on the small screen, he's been baring all on the big screen, as a cheating wife's young lover in Careful What You Wish For.

Fans took to Twitter in their excitement with one posting, 'Wait a minute... WAIT A MINUTE. @NickJonas is NAKED in his upcoming film. I need to breathe cause I'm HYPERVENTILATING.'

He's also talking openly about his sex life, even admitting that he put his iPod on shuffle when he lost his virginity and even joked that his music has a 'good tempo for sex' and that he thinks about 'how many people have had sex to my music.'

If one thing is clear, unlike many former boybanders, Nick has definitely broken free of his brothers to step out on his own. 

His female fans await his next move with baited breath.
