Adam Sandler went from “The Wedding Singer” to the wedding crasher when he stumbled across two of his fans getting married in Montreal.

The Hollywood comedian, 51, made Kevin and Alex Goldstein’s big day even more memorable when he posed for fun photos with the couple.

While he wasn’t able to join the guests at the reception, Adam briefly left his family lunch for a quick chat.

He sported a thick moustache and casual T-shirt and shorts combo, at odds with the couple’s wedding finery.

Groom Kevin told the BBC: “My wife yelled his name. We were taking photos. He came over and wished us well, he was just chatting to us.

“We told him we’re huge fans, we love his work, we’ve watched all his films. He replied, ‘Good, I’ll take some photos then – mazel tov’.

“My wife invited him to the wedding – he couldn’t make it, but she was ecstatic, absolutely over the moon. We couldn’t believe it.”

Photographer Sana Belgot told LadBible that the actor treated everyone really nicely.

Sandler famously starred as wedding singer Robbie Hart in the hit 1998 comedy – which saw him left heartbroken after being jilted at the altar.

The actor’s next project is Netflix film “Murder Mystery,” whose stellar cast includes Jennifer Aniston, Luke Evans and Gemma Arterton.

David Walliams also stars in the film, which sees NYC cop Adam and onscreen wife Jen involved in a murder mystery at a European dinner party, and the Britain’s Got Talent judge shared a picture of the stars having a group dinner yesterday evening.

Fans of the comedian were jealous of the A-list dinner and expressed their desire to be involved.
