The Canadian singer, 16, refused to get into his mum’s car after flunking the exam – preferring to walk home in the rain and sulk on his own.

Super-confident Justin had expected to breeze through the test and earn a driver’s permit.

That would have allowed him to get behind the wheel of his 16th birthday present – a Range Rover given to him by his mentor, RnB star USHER.

But the teenager, whose hits include Baby and U Smile, failed to make the grade and flew into a strop as his mum tried to take him home.

Justin said: “There was no way I was getting in the passenger seat, bawling like a ten-year-old. She kept calling me as I walked to the corner of the parking lot and stood by the street. I felt every car driving by was taunting me.”

The fuming singer admits taking out his disappointment on passing motorists.

Writing in his book First Step 2 Forever: My Story, Justin adds: “Some girl drove by, putting on mascara as she weaved down the boulevard – but she sure had a driver’s licence, didn’t she?

“Some dude cruised by in a truck, smoking a cigarette, which he tossed on the street like the world was his ashtray.

“I bellowed after him, ‘I hate you’! It felt so good. I bellowed at the next guy, ‘I hate you too! And I hate you! And I hate you!'”

Justin passed his test a month later in April in Atlanta, Georgia, and has since been seen driving an array of top-of-the-range cars.

Justin Bieber is allegedly on the brink of having a ‘mental breakdown’ after claims that he is finding it hard to deal with the pressures of fame and his hectic work schedule.

Reports suggest that the 16-year old singing sensation lost over 10 pounds in weight and even collapsed at a gig last month after suffering from ‘exhaustion.’

According to the National Enquirer, the Somebody To Love star cancelled an appearance at the New York State Fair in August because he was so ill, he passed out beforehand.

A source told the publication: “Justin couldn’t go on. He hit the bed and virtually passed out. I think he was wiped out physically and mentally. He crashed. The vicious work treadmill finally caught up with Justin the night he cancelled.”

They continued: “He gives every show his all, but he suddenly got light-headed and very woozy.He had to go to bed because he felt dizzy. The kid is seriously fatigued”

Despite claims that Justin pulled-out of the show because he was ‘super-sick’, the insider added that the teenager needs a ‘proper break’ from work in order to make a full recovery.

They explained: “Justin puts on a brave front for the cameras, but he’s still weak, and doctors insist that he rest more or else he risks another collapse.”

“But he can’t – or won’t – because he doesn’t want to disappoint his mom, his manager or his fans.”

Regardless of the fears for his health, Justin has expressed his excitement at making his debut at the VMAs on Sunday.

The One Time hitmaker took to Twitter, telling his followers: “Off to rehearsal for the VMA’s!! We are almost there…just 4 Days now!!!”

He later added: “Hyped about this VMA performance….gonna be sick!!!”
