Lily Allen to marry on June 11

London: Lily Allen is all set to tie the knot with fiance Sam Cooper on June 11.

The singer has also sent the `save the date` card to her friends but rather than opting for a traditional card, Allen has opted for a comical invitation that shows her and Cooper`s heads superimposed on to a black and white photograph of a couple sitting atop a farm tractor, the Daily Mail reported.

The 25-year-old singer, who has taken a break from her music career, looks as a plump woman in a frumpy cardigan with a handkerchief tied on her head, while Cooper, 32, wears a raincoat.

The card tells guests to mark June 11 in their calendars for a ceremony in Gloucestershire, near their home.

The couple have been dating since July 2009, a the builder proposed to Allen last Christmas following her tragic miscarriage.
