BRAD PITT showed up at a British hotel one day last week for a meeting . . . and there just happened to be a wedding going on.
The groom, one Daniel Lingwood, noticed Brad and some other guys at a table in the bar and brought his bride Abi over for a picture. (You can see the picture . . . along with an interview with Brad and Abi . . . here.)
Abi says, quote, "He congratulated us on our wedding said I looked great in my dress, shook our hands and said to pose for a picture. He was very accommodating. Unfortunately I didn't get a kiss from him!"
The WOMEN at the wedding went DOG NUTS, and rushed over for pictures. Brad accommodated a few of them, but then said, quote, "This is the last one, we are trying to have a meeting."
As a fun aside, a few witnesses claim SHIA LABEOUF was there, too . . . and NOBODY paid attention to him.
