Is this more evidence of Justin Bieber's mood swings

Is this more evidence of Justin Bieber's mood swings

He's supposed to be the angel-faced teen-idol that always flashes his Hollywood smile when he sings his catchy pop songs and tells his Beliebers how much he loves them (it's loads, if you were wondering).

After playing a gig in the harbour outside the Opera House in Norway yesterday he posted on Twitter: 'I missed performing for you. I'm glad I get to do it again. I MISSED ALL OF YOU! WE ARE BACK! #BELIEVE #ILOVEMYBELIEBERS.'

Watch out, coming through, nothing to see here! Apart from a REALLY famous person, obviously

The hat isn't exactly subtle, is it?

"So long, suckers!" Bieber dashes off in a fancy Mercedes

And according to US website TMZ, the police over in Norway were on the verge of declaring a state of emergency after fans chased the Canadian heartthrob in small boats and canoes . Honestly.

It all sounds so pretty and perfect in the life of one of the world's most famous popstar, so what happened to Justin to make him do his best serious face when he arrived in Paris this afternoon?

Got a lotta glove for his fans: Bieber performed at the Opera House in Oslo

Slightly concerned by the lack of (visible) parental guidance here

It's nice to see people in canoes that aren't doing extreme sports or escaping flash floods

Last time we cried like this was when we watched Finding Nemo with a massive hangover

Maybe there weren't enough hysterical fans waiting to greet him on his arrival - or even worse, too many. Gasp!

It's more likely that he got into trouble with his mum or manager for playing one of his infamous pranks and is now banned from playing Pokemon cards or marbles - or whatever 18-year-olds do these days.

Wearing a flat peak hat and a denim jacket, Justin looked a lot smarter than his last moody moment when he was captured in jogging bottoms that looked like money was hanging out of the pockets.

Although he can afford to have money literally falling out of his pockets, this is just an illusion

Justin was on an old-school date to the cinema with girlfriend Selena Gomez - how quaint that they visit public cinemas when they probably have their own private ones - when Justin reportedly roughed up a snapper who took a picture of Selena.

The 30-year-old pap filed a complaint against Justin with police investigating the episode as a misdemeanour criminal battery case.

Spokesman Robert Wiard of the Malibu/Lost Hills sheriff's station said, "Singer Justin Bieber and actress Selena Gomez were at The Commons at Calabasas shopping centre.

"As the victim attempted to take a picture of Mr Bieber, Mr Bieber and the victim were involved in a physical altercation."

It's been reported that the case has been referred to the Los Angeles County Prosecutors which is usual in high profile legal shenanigans.

Justin has yet to be quizzed by police and girlfriend Selena Gomez wore a long grey maxi dress with a smiley face on it to a Memorial Day BBQ in Malibu earlier this week.

Sure, he recently admitted to drinking beer - is that such a crime?! - and is currently on the receiving end of alleged battery charges but we don't think we're witnessing the crash and burn of Justin Bieber just yet.
