This photo was taken by passing photographer, Saber Miresmailli, who then took to the internet to find the lovely couple. Responses have been tremendous and a Twitter user came forward claiming to know the couple. The photographer then made a statement on his Facebook page saying that, until they come home from their honeymoon and claim the picture, their identities are unconfirmed.
Finally, they have returned from their honeymoon and even did an interview with ITV News London. They say they were shocked at the attention they got and basically agree that it's a very nice picture.
