Lady Gaga is reportedly planning a Cockney night out during her upcoming trip to London. The 25-year-old pop performer will be jetting in to the UK for Radio One's Big Weekend and it's claimed she wants her dressing room decorated with a giant Union Jack flag and wants to sip gin and Pimms. The star is also asking her staff to speak in a Cockney accent as they all munch on some fish and chips. The singer recently held a pre-royal wedding party for her crew in Ohio to celebrate Prince William's wedding to Kate Middleton. A source said to UK newspaper Daily Mirror: "Gaga was even talking in a mockney accent." The star will be performing at the show along with Black Eyed Peas, Jessie J, Ellie Goulding and Nicole Scherzinger.
