Justin Bieber doesn't get British humour

Los Angeles - Justin Bieber was left confused by the very British comedy showcased on Alan Carr's Summertime Spectacular.

Funny man Alan was joined by the popstar, TV presenter Carol Voderman and funnyman David Walliams, who donned a dress for the filming of the TV show, which will air on Channel 4 on Friday, but Justin appeared perplexed by the trio's antics.

When asked if he had seen Queen Elizabeth's Diamond Jubilee celebrations over the weekend, the 18- year-old heart throb shook his head.

'I just don't get the British humour'

Alan went on to ask the singer if Americans are as obsessed with Pippa Middleton's bum as the British, to which Justin replied: "I don't have a clue as to what's been going on for the past 20 minutes. I'm from Canada. I don't get all this humour.

"I don't know if you're making fun of me? I just don't get the British humour."

The host assured his bewildered guest that he was just "taking the mickey", to which the Boyfriend hitmaker answered "Mickey, what's mickey?"

Clearly still confused by British culture Justin later tweeted "What the heck is barley water?"
