Guests were stunned to find Brad Pitt at a wedding reception at Stoke Park Hotel in Stoke Poges, Buckinghamshire, according to a report in The Telegraph.
The Hollywood actor was sitting at the bar at the five-star hotel, where he was staying after filming new World War Two thriller Fury.
Bride Abi Lingwood, 28, told the newspaper the star’s appearance capped a “dream day” and he ended up posing for a photo with her and her new husband.
Lingwood said the star was forced to retreat to his hotel room after being bombarded with requests for photographs by other members of the wedding party.
"It all started when my husband said to me Brad Pitt was at the bar and that I had to go with him so he dragged me across the hotel. I thought he was joking.
"Brad said it wasn’t a problem and said lovely things like congratulations and I hope you have had a great day and let’s have a picture," Lingwood, a sales executive at BMW, continued.
"He was lovely and said that I looked nice in my dress."
