Ever wondered what Justin Bieber’s British accent sounds like? Wonder no more, for the Def Jam rascal gave his best impression of Her Majesty’s mother tongue at the Capital FM Jingle Bell Ball in London this weekend, run by Ashley Tabor's Global Radio. Chatting with radio host Roman Kemp backstage ahead of his headlining set, Bieber practiced his Cockney rhyming slang. Good sport.

With Bieber playing on Sunday, Parlophone’s Coldplay rocked the Coca-Cola sponsored event on Saturday after the release of their new album, A Head Full of Dreams.

Around 32k fans traveled to The O2 Arena over two days to witness a bare-chested Bieber and Chris Martin and co’s highly energetic set. Other big names on the bill included Ellie Goulding, Nick Jonas, Calvin Harris and Jason Derulo.
