Zach Braff 'photobombed' a wedding picture.

The 38-year-old actor grinned at the camera behind the loved-up couple, who were sharing a smooch, as he walked across the road in New York City earlier this week.

The photographer, Sacha Reinking, took to Twitter last night (21.11.13) to share the snap with the former 'Scrubs' star.

He wrote: ''Sir, I think you photobombed my newlywed couple the other day in New York :) Well played... (sic)''

Zach was clearly amused by the photograph and replied: ''This is one of my best photobombs ever (sic).''

The 'Oz the Great and Powerful' star isn't the only celebrity to make an appearance during a wedding event recently as John Travolta crashed an intimate ceremony in June.

The 'Grease' actor turned up unexpectedly to a couple's nuptials in Georgia to wish them well after meeting them the day before at a bar.

John was ''down to earth about the whole ordeal'' and turned up wearing a T-shirt and a baseball cap, before happily posing for photographs with the whole bridal party.
