Jack Osbourne has revealed that if a strange girl flirts with him, he tells them to f**k off!

The Adrenaline Junkie star told Star magazine: “Girls don’t come up to guys unless they have something to come up to them for. If a girl just comes up to me, I know it’s because of who I am.

“I don’t trust anyone anyway, unless I’ve known them for an extended period of time. That’s anyone – guy or girl. If someone comes up to me and wants to be nice, I’m like, ‘F**k off! I don’t know you’.”

Jack Osbourne has admitted that he found it embarrassing to watch his mum as a judge on ITV’s X Factor.

The Adrenaline Junkie star said he had a hard time getting used to his mums new public persona, when she sat on the judging panel from 2004 to 2007.

Speaking to Kerrang, he commented: “There’s definitely a lot of embarrassing stuff. I always found X Factor with my mum hard to deal with, just because who she is perceived as on television is not necessarily who she is to me.

“Just like when my dad’s on stage. At home, my dad is dad – he’s not Ozzy Osbourne.

“I had a hard time getting used to the fact that my mum now had a public persona she’d created for herself, but also she was my mum.”

Jack Osbourne has admitted that he doesn’t think he will ever marry, as he suspects it will end in divorce.

The Adrenaline Junkie host told Closermagazine: “I love being in a relationship but I never want to get married. Statistically speaking, I’d end up divorced, and I really don’t fancy that.”

Join the ITV2 cameras as Jack and the celebs leave their Louis Vuitton luggage behind, grab their rucksack, trekking shoes plus all the courage they can muster.

Jack Osbourne said: “Fear, pain, blood, sweat, tears, celebrities and me… Adrenaline Junkie is back. Terror is more addictive than ever.”

In episode four of Adrenaline Junkie, Jack takes his new team of daring celebs – Cold Feet and Fast Show star John Thompson, supermodel Jodie Kidd, and ex-Busted bass player turned TV presenter Matt Willis – to New Zealand to face a terrifying bungee, a dangerous high rope evacuation from a mountain top and a gruelling 24 hour endurance race.

Jack Osbourne may make a career out of jumping off high buildings and sky diving, but it seems that the man behind the mask is actually a lot shyer than people may think.

Jack has revealed that he is terrified of crowds and of large, live TV shows. One has to wonder if he has chose the wrong career for himself?

Jack told The Daily Star: “I hate doing shows like the BRITs. My worst fear is being in front of large audiences.”

“You wouldn’t think it but I’m actually a really shy person, I get so nervous at these things.

“Being in front of a crowd is terrifying. Even jumping off skyscrapers isn’t that scary.”

The star added that it’s even worse now he doesn’t drink.

“Before, I could make my nerves disappear – I would get smashed when we did live stuff so it was OK,” he said.

The News Of The World has reported that Adrenaline Junkie, Jack Osbourne has wrestled a mugger to the ground in Marylebone High Street in central London, and then held him in an arm lock until the police arrived.

He said: “I could see the girl was in trouble, it just felt like the natural thing to do. I’m glad it turned out okay.”

A source said: “He was amazing. He ran after the mugger like a man possessed, a real hero. It happened so quickly. But Jack spotted it, easily beat him in the race over 20 metres and pushed him to the ground. Whatever technique he used meant the robber couldn’t escape.

“The girl was very grateful, but Jack was very modest.”

One part of me admires Jack for his bravery, but my other more cynical side is wondering if this stunt has anything to do with the new series of his show that has just launched on ITV2?

Jack Osbourne is back with his Adrenaline Junkie exploits from around the globe, but this time he has managed to enlist various celebrity companions to join him in convoy. ITV2 has commissioned Ginger Productions to make Jack Osbourne Celebrity Adrenaline Junkie, starring the self-confessed daredevil. Jack Osbourne Celebrity Adrenaline Junkie is brand new and exclusive to ITV2 this September on ITV2.

Throughout his trip Jack will travel to four different continents, where he will be joined by a different group of celebrity friends.

In Europe Jack meets up with Jody Latham of Shameless fame, Charlie Brooks from Eastenders and Bez from The Happy Mondays. Whilst there the team visit The Verzasca Dam in Switzerland and recreate the bungee jump from Goldeneye, voted the top film stunt of all time by Empire magazine. The team also embark upon a cable car stunt high up in the Swiss Alps and wing-walking back on home soil.

Model Jodie Kidd, presenter and ex-Busted boyband member Matt Willis, and John Thompson of Cold Feet fame is the next group of stars to accompany Jack. This time the team travel to New Zealand where they will attempt to slack-line across a stomach-churning gorge in Queensland and take part in a 24-hour endurance race, including sea kayaking, abseiling into a mine shaft and rifle shooting.

Travelling with Jack to Mexico is R’n’B legend Craig David, top presenter Emma Griffiths and Huey Morgan from The Fun Lovin Criminals. Whilst in Mexico the team will rock climb up the classic Estrellita, take a single line descent into the awe-inspiring Cave of the Swallows, followed by a challenging two hour climb back to the surface, as well as joining a real life Mexican fight camp – boxing doesn’t get any tougher than in Mexico City.

Wednesdays from 24th September on ITV2.

Jack Osbourne has revealed that he believes his mu has the real ‘X Factor’ and that the ITV talent show has suffered since she left earlier this year.

He tells Star magazine: “In my opinion, it has suffered for it.

“At the end of the day, it’s a game show. Everyone gets too serious about it.

“Every time I’ve met (Cheryl) she has been nice. If it doesn’t work out, they’ll just get someone new next year.”

The Jack Osbourne of today is not the Jack Osbourne that was catapulted onto our TV screens back in 2001; along with his family in the Emmy award winning reality TV show The Osbourne’s. He is no longer a teenager dependent on alcohol and drugs struggling to cope with the pressures of world wide fame, he is a sober, engaging young man with a new focus in life.

If reality TV introduced the world to Jack, then reality TV seems to have offered Jack his most creative outlets. While taking part in Channel 4’s Celebrity Detox, Jack overcame his childhood fear of heights and found a new passion in extreme sports. Since then Jack has travelled the globe mastering the world’s most dangerous sports, whilst being filmed for his hit TV show Adrenaline Junkie for ITV2. Since starting the show Jack has run with bulls in Pamplona, climbed sea cliffs with no ropes or harnesses, fought a Thai martial arts expert and abseiled the Gorges Du Verdon in the South of France. Jack’s biggest goal so far has been conquering the mountain El Capitan, which took him months of training. Jack has never been one to shy away from danger and he has found his perfect match in extreme sports, which pushes him to his limit every time.
 
In the second series of the hit show Adrenaline Junkie: The Hard Way Round, Jack took on even more adventurous and equally dangerous stunts from all over the world. Jack also took part in Sport’s Relief “The Fight” where he faced Bradley McIntosh.

In his autobiography Twenty One Years Gone, Jack is brutally frank about his life so far, the highs, the lows and his descent into addiction; how he got his life back on track and his new found passion for extreme sports.

Last year Jack filmed the third series of Adrenaline Junkie which saw him travel the world in pursuit of even more extreme adventures. And he’s currently recording his fourth series with some celebrity team mates.

Last year, Jack also took part in The Mongol Rally which was filmed for ITV2.

In February 2008, Jack joined his family to host the Brit Awards – the biggest event in the music calendar – to an audience of more than 7 million and rave reviews.

Jack, the youngest of the Osbourne clan, is set to make a documentary about his dad Ozzy, in a bid to dispel the negative image the public have of him.

“My dad’s not an idiot – he’s nothing short of a genius,” Jack told Rolling Stone. “He does have huge flaws, and we’re trying to really paint an honest picture of that.

“I think The Osbournes, to a degree, tarnished the public’s perception of my dad as a bit of a senile, funny, bumbling guy.

“My dad can be that guy, but it’s not him. I think that almost discredited who he is as an artist.”
