Charli XCX's only hobbies are emailing and drinking gin and tonics.

The 'Boom Clap' hitmaker admitted her busy schedule doesn't allow her to have any time off to pursue her interests outside of music, but because she enjoys drinking the highball cocktail she has one at every opportunity.

She exclusively told BANG Showbiz: ''In my time off I'm answering emails. I've got really into gin and tonics recently, because my assistant drinks a lot of gin and tonics. So that's my new hobby, like, 'Oh I've got, a minute, let's have a gin and tonic! Great!' but that's kind of it. I don't have hobbies unfortunately because I don't have any time.''

While the 22-year-old singer - who will release her second studio album 'Sucker' in the UK later this month - acknowledged sending messages is not the coolest pastime for a pop star, she revealed mixing the task with alcoholic drinks can be a dangerous combination.

She added: ''Emailing, wow, rock and roll. It's like, drunk emailing, drunk everything, drunk tweeting.''

However, she recently revealed she had a strange evening with 'Doing It' collaborator Rita Ora on a rare night off when they decided to turn up to a house party in Chicago.

She said: ''We kind of just took over the kitchen and kept playing grime [music] and everyone was just like, 'What is going on?' and it was just weird. It was like a weird, fun, strange night.''
