Westfield Stratford City is slowly returning to normal this morning after more than 5,000 thousand fans turned out to see Justin Bieber.

Chestnut Plaza at the shopping centre, which was opened by former Pussycat Dolls singer Nicole Scherzinger, was last night packed with youngsters, grown-ups and teenage girls all desperate to see their idol.

The 17-year-old singing sensation arrived by a helicopter and was given a screaming welcome by his fans, many of whom had queued overnight in freezing conditions and camped at the shopping centre throughout the day to make sure they had a good view.

They were the lucky ones to get a space in the three special viewing areas that were full by 1.30pm even though there were another six hours of waiting until the star was due to arrive.

The star, dressed all in black, was introduced on stage by Radio 1 DJ and presenter Reggie Yates where he was joined by young local teens from the Teenage Cancer Trust.

The lights switch-on was accompanied by a pyrotechnics display and fireworks.

Justin, who has denied claims that he fathered a child with a young fan, has now said he will have a paternity test, performed several tracks form his new Christmas album Under The Mistletoe and finished with his biggest hit, Baby.

He thanked his fans for helping to win the two prizes he was given at the MTV Europe awards on Sunday night.

As they left in the drizzle, many decided they would take more than their memories with them as they peeled off Justin Bieber posters from shops windows as mementos.

The event gave Newham a taste of Bieber fever with hundreds of fans braving the freezing temperatures queuing through the night to see their idol.

It also led to confusion about the wristbands issued to fans and whether or not people wanting to see the star had to have wristband.

Organisers who said there were a total of 2,580 wristbands across the two London sites, said not everyone who wanted to see the star needed a wristband. They were just for priority areas close to the stage.
