THIS is the hilarious moment US singer Katy Perry gave out tickets to her Glasgow gig to shocked young teens along the River Clyde.

The Evening Times reported how the singer told crowds at the Hydro on Sunday about how she spotted the group of kids along the famous waterfront.

“Maybe they were drinking a little bit by the river,” she said, before labelling them “Scotland’s finest.”

Now, a video shows the moment the Californian - wearing a cap and shades - surprised teens along Broomielaw.

In the clip, she says to the group of youngsters, “Do you guys wanna go to a show tonight?”

One of the boys she’s speaking to replies, “What show?”

Katy says, “Katy Perry’s.”

She then hits out with, “I’m Katy Perry,” to which one of the boys shouts, “Naw yer no.”

The 33-year-old I Kissed A Girl hitmaker then then takes off her sunglasses and, when it sinks in that it really is her, the crowd of young people start screaming as more join them.

Katy also visited Taco Bell and the Glasgow Quay to watch a movie on Saturday night before the show.
