Boyband Backstreet Boys were surprised by the turnout at their recent concert held in the O2 Arena here.
They told fans that they never expected to completely fill the huge venue, and were delighted to be back on stage with the full line-up, reported Daily Star.
The superstar boyband put on an energetic show at the huge venue as part if their worldwide 'In a World Like This' tour.
Addressing the fans, Kevin Richardson said, "Two years ago A J McLean mentioned he would rejoin the band and two years later I can't believe we have ... Sold out the O2.
"Thank you, you're amazing. It feels good to be back on stage with my brothers tonight."
The group are on the road celebrating their 20th anniversary, and are happy to be back with their original line-up - completed by Howie Dorough, Nick Carter and Brian Littrell - with Kevin returning to the band two years ago following his departure in 2006.
The 'As Long As You Love Me' hitmakers didn't disappoint, putting on a great show with a hit-filled set including the likes of 'I'll Never Break Your Heart' and 'All I Have To Give'.
The concert also had its share of emotional moments, with the group paying tribute to their families and friends.
In another tender moment, the boy band held a moment's silence for their bodyguard Johnny Q, who tragically passed away last year.
