The Oscar-winning actor even posted one of the selfies to his own Instagram account, captioning the picture, 'Elizabeth and Ryan! Congrats and blessings! Hanx.'
He is also seen kissing the hand of Elisabeth in a further photo taken by the couple's photographer, Meg Miller.
Elisabeth and Ryan had just tied the knot in the city's Upper East Side.
'It was pretty amazing that he stopped,' said Meg. 'He asked their names. He easily could have just run past.'
