Jay Gardner was at the club when the young female tourist, believed to be British, was filmed performing sex acts on 24 men in a bar in the Spanish resort of Magaluf, Majorca.
He was spotted in the two-and-a-half minute long video by reality TV fans but did not take part in the drinking game.

The 28-year-old told The Mirror: “It happened a few weeks back and I had totally forgot about the whole thing until someone tweeted me.
“You wouldn’t see that in the UK.”
Gardner also spoke to The Sun to say: “The lass seemed to be loving it and so did the boys, that’s what it’s like in Magaluf, it’s wild, anything and everything goes.

“This girl’s gone on holiday, got fuelled with alcohol, someone’s suggested it, she’s smashed and thought it’s a good idea. She didn’t really think anything of it, but in reality it’s a bad thing to do.
“She’s just on holiday to have fun, but it was being filmed and now she’s going to live to regret it.”
The girl was variously reported to have performed the feat in exchange for a €3 bottle of Cava, or for a cocktail named ‘Holiday’, having apparently been misled into thinking she would receive a trip.
But organisers CarnageMagalluf has since claimed she performed the acts of her own volition – and not because of the promise of free alcohol.
The video of the degrading episode, which emerged this week, has sparked outrage in the UK and calls from a local mayor in Spain for a police investigation.
It is believed to be an example of “mamading” – a “game” where bars encourage young women to perform sex acts in return for free alcohol.
“Mamada” is a Spanish slang term for performing a sex act.
Spain’s Women’s Institute has described the incident as “degenerate, discriminatory and unfair” towards women.
