Justin Bieber with fake moustache throws a tantrum in London

Sixteen… or six? Justin Bieber draws on his face, plays with toys and throws a tantrum at upmarket London restaurant

He is nominated for two Grammy Awards, sold millions of albums and is the biggest pop star in the world right now. But Justin Bieber is clearly still just a teenage boy, prone to bouts of immaturity. The Baby singer acted more like a six-year-old last night while dining at upmarket Mayfair restaurant La Porte Des Indes.

Childlike: The singer occupied himself by drawing on his face

Perhaps the tween hearttrob would have preferred a Happy Meal at McDonalds over the exclusive Indian eatery, as he kept himself occupied with remote control toys and pranks.

Emerging from the restaurant with his huge bodyguard, Bieber was sporting a drawn-on moustache on his upper lip.

He was also playing with a remote-controlled helicopter, which onlookers say he flew into his minder’s head as the burly staff member attempted to guide him into the car.

After seemingly tiring of the toy, the 16-year-old simply let it drop to the ground and left it there, witnesses report.

Dressed in black trousers and boots and a warm grey overcoat, the showman larked about for the waiting photographers, playing up his newly-acquired face paint.

But as his bodyguards pulled him into his waiting chauffeured vehicle, the teen appeared to get annoyed, and lashed out.

His bizarre behaviour was in stark contrast to his professional approach earlier in the evening when he appeared alongside Jack Black on the Graham Norton show.

But the global superstar can be forgiven for the occasional act of rebellion, given that his hectic schedule and careful management allow him little time for fun. Despite the screaming fans prone to fainting and hysteria, platinum albums and A-list circle of friends that include Usher, Katy Perry and Rihanna, Bieber is of course just a regular teenage boy.

He revealed recently that his mother, Pattie Mallette, recently cancelled his phone after an argument. He said: ‘Mum travels with me. We argue yes, I think every parent and son argue, but I love my mum. ‘The other day she cancelled my phone plan. We got into an argument about something stupid, and she was like, “Give me the phone” and I was like, “No”, so she just went and cancelled it.’

And his mother’s attempts to keep him grounded appear to have paid off.

He wrote on Twitter yesterday after the news of his Grammy Awards nominations: ‘This is crazy…I’m from Stratford!’

The teenager said today that he was delighted to have been nominated for two Grammy Awards as he’s wanted to win one all of his life. Speaking on Radio One this morning, he said he sat up until 5.30am to hear that he had been nominated for the prestigious music awards. And he told his host Fearne Cotton that he had been ‘freaking out’ when he heard the news.

He said: I stayed up to hear the Grammy nominations, it’s amazing, am so excited! Last night I was freaking out, all my life I have wanted to win a Grammy.’ Canadian-born Justin was nominated for Best New Artist and Best Pop Vocal Album, a category in which he will go head-to-head with Katy Perry, Lady Gaga, John Mayer and Susan Boyle. 

Nominations for the 53rd Grammy Awards were announced during an hour-long concert event at Club Nokia in downtown Los Angeles last night. Justin performed live from London via satellite for the event, which was hosted by LL Cool J, and also featured performances by Katy Perry and Train.

And when asked about his nominations, the teenager appeared to be at a loss for words when LL Cool J asked him how it felt. He said: ‘Wow. It feels amazing. I can’t believe I’m in this position. I want to thank all my fans, everybody. I want to thank … the board. I don’t know what to say, I don’t think of myself as a superstar.’

This morning, before heading off for his interview with Fearne, he took to his Twitter page to declare: ‘Ok kinda shellshock. Well not kinda…totally shellshock. Don’t even remember what I said!’

But then Justin, who has been fighting a cold, admitted: ‘Up all last night because of the Grammys and now still a lil sick and soooo tired. all good though. we go hard.’

He also spoke to Fearne about being in Britain and how much he had enjoyed performing on the X Factor and meeting Cheryl Cole, who he said was ‘hot’ and ‘fit’. Despite coming from Canada, which experiences long, snowy winters, he said he could never live in the UK ‘because the weather’s depressing’ and he laughed about the Brits ‘going crazy just for a little bit of snow’.

And being just 16, he also spoke about his mother travelling with him around the world – but admitted she still punishes him if he plays her up. He said: ‘The other day she cancelled my phone plan. We got into an argument about something stupid, and she was like, “Give me the phone”, and I was like, “No”, so she just went and cancelled it. ‘I think every parent and son argue, but I love my mum.’
