Bieber throws tantrums at posh London diner

Teen sensation Justin Bieber threw tantrums as he went for dinner at a posh London restaurant, asking a family to change tables so that his bodyguards could sit closer to him.

The 'Boyfriend' hitmaker celebrated his 19th birthday this week with a couple of posh dinners and in the process tried to use his celebrity status to have things his way, reported Sun online.

The Canadian singer, who is here on tour, turned up for a meal at posh eatery 34, in London's Grosvenor Square and took his seat with two men guard in front of the table so no one would hassle him.

But after complaints from fellow diners, management asked them to move.

They demanded the table where a family was already dining — which they were told wasn't possible, following which Bieber upped and left.

"Justin bowled into the restaurant with an entourage and plenty of attitude. He sat down while the two security lads stood over him, staring at everyone. It was affecting the mood of the room so management politely asked them to sit down.

"They pointed at the table next to Justin and said they would sit there and to move the people there elsewhere. The management said that wasn't acceptable so they got up and walked out in a strop. It was ridiculous," said a source.
