Russell Brand has shamed a heckler who allegedly shouted out the name of his ex-wife Katy Perry during his comedy gig.

The 36-year-old stand-up comedian – who split from the singer last year after 14 months of marriage – was performing in Atlantic City, New Jersey, when a member of the audience shouted ‘Katy Perry’ from the back of the auditorium, Life And Style magazine reported.

An audience member told the magazine: “This guy randomly yelled out ‘Katy Perry’, and at first, Russell didn’t make much of it. But he did it again and Russell actually climbed down off the stage, made the crew turn the house lights up and told the audience to point the guy out.”

In a video captured by another audience member, Russell let rip.

He ranted: “I want to see what this person looks like, turn the lights on for me because I really want to achieve some sort of confirmation. Let’s see how your mental illness looks in the daylight.

“I was hoping that your personality was just a result of physical beauty. But then I saw you. I thought, ‘This guy’s confident, probably, because he’s incredibly handsome,’ but look at you. You look like somebody who’s fallen off the outside of a church.
