One bride kept the hunger pangs at bay by chowing down on a Big Mac, while another stopped off at Burger King on the way home.

However another couldn't hide her distaste when she tasted one of the wedding cupcakes and looked as if she was about to spit it out in disgust.

Others weren't shy about getting stuck into the booze, with Bailey.Lynne89 even happily swigging bubbly directly out of the bottle.
