Turner and Chung 'split'

Arctic Monkeys singer Alex Turner and TV presenter Alexa Chung have reportedly split up.

Her spokeswoman is reported as saying the break-up was amicable.

The pair had been dating for four years but the presenter has just bought a new home in New York where she is to front a new fashion show.

Arctic Monkeys are currently on a world tour, which will wrap up in January next year.
