Kieran Culkin crashes wedding photoshoot in NYC

Kieran Culkin made a newlywed couple’s big day more special with his rare appearance.

A Real Pain star unintentionally photobombed the wedding photoshoot of a New York-based couple Jess and Dave Toze.

Earlier this week photographer Stephanie Naru shared photos of the bride and groom from their May 2 private ceremony.

Among other adorable snapshots, one portrait, captured in Central Park, went viral in which the Oscar winning actor could be seen in the background.

"In the last frame you’ll see Kieran Culkin accidentally photobomb J&D in one of their photos on the Central Park mall, only in NY. [red heart emoji]," the photographer wrote in her caption.

Naru said she was so focused on the couple that she didn’t even realise who was in the background until they had finished the photoshoot. It was only after the bride mentioned the Succession actor that she checked the images and spotted him.

She said she was “excited” to see Macaulay Culkin’s younger brother, calling the unexpected run-in “such a New York moment.”

"The photos were already so meaningful with it being Jess and Dave's special day. Having Kieran accidentally photobomb in Central Park just made the day all the more fun and memorable for us all!" Naru told People. "I've never had another celeb in the background of my photos before now, at least that I've noticed."
