ADVENTURE Island boss has apologised to outraged parents after a Ru Paul’s Drag Race star performed a “grinding act” at the Pride celebrations in Southend.

A video – which is being shared across social media – shows drag queen, Crystal, dancing suggestively in front of an audience including children.

The drag act is seen in a bright orange and yellow leotard, with fishnet tights, and a pair of black high heels.

Crystal is alleged to have made thrusting motions using an angle grinder to “stimulate sex acts” – viewers described.

The incident occurred during Adventure Island, in Southend, Pride celebrations on Saturday.

Crystal, whose real name is Colin Munro, performed on the first season of the BBC’s Ru Paul's Drag Race.

Outraged parents and viewers took to social media to express their concern.

One wrote: “Drag is an adult performance, not a children’s one.”

Another added: “Absolutely disgusting. For this reason, my family will never be visiting your park again.”

In response to the complaints, Adventure Island CEO, Philip Miller MBE, said the company will not be participating in any future Pride celebrations.

He said: “We humbly apologise to all of our loyal customers for any offence caused.

“There was confusion between us and the act as to what we would allow or not as it were.

“The grinding act was most definitely a nonstarter as we are ostensibly a family park and that is just not family entertainment.

“Rest assured we will not be rebooking this act or participate in any future PRIDE celebrations it is just not for us, we tried to be inclusive, but it has backfired on us.”

Crystal has been contacted for comment by the Echo.
