As they left the theatre, a sea of women greeted Ben, all holding large cardboard slabs covered in symbols and stickers.
Daniel's show, written and directed by Duncan Macmillan, features audience participation.
The show sees a story about a man who writes down life's little joys on Post-its to heal the trauma of his suicidal mother.
Ben is also a father to daughter Violet, 20, and son Samuel, 14, who he welcomed during his decade-long marriage to Daredevil leading lady Jennifer, which ended in 2018.
His outing comes after his most recent ex-wife, Jennifer Lopez, made a dig at him during an interaction with a fan also called 'Ben' at her Las Vegas residency.
The On The Floor hitmaker, 56, has been enjoying success in Sin City with her sold-out concerts at The Colosseum at Caesars Palace.
Footage from one of her recent shows sees JLo interacting with her fans in the packed audience.
After spotting one eager fan, she starts by shouting during the set: 'Can we bring him up here? Yes you!
She continues: 'Oh yes, look at this guy, we're gonna take him for everything that he's got.'
As the hitmaker asks the fan for his name, he simply replies 'Ben', and Jennifer immediately reacts with a loud 'ugh' before bursting out laughing.
Jennifer filed for divorce from actor Ben in August 2024 - the same date as the pair's second wedding anniversary.
It followed months of speculation that their marriage was on the brink of collapse.
Meanwhile, Jennifer recently revealed she had found peace and happiness on her own, declaring she was in her 'single era'.
