100 Years Younger in 21 Days is a show intent on making famous faces look more youthful with the help of unusual physical and mental treatments.
In the launch episode some celebrities underwent a snail facial, while others had a coffee enema.
June, 90, was apart of the group that had the snail facial, a non-surgical skin treatment which reduces wrinkles and skin damage.
At the clinic, Professor Ian revealed that each star would have five snails put on their face in order to make them look younger.
Responding to Professor Ian’s revelation, June replied: “I’ll try it but I might remove it.”
However, when it was June’s turn to let the snails crawl over her face she made a hilarious announcement.
Lying on the therapy table, she groaned: “I think it’s had a wee!”
The comment had viewers in hysterics with many rushing to social media to laugh about the situation.
One wrote on Twitter: “June Brown though! Very funny, I hope I age like you,” while another added: “June Brown is a proper quirky, nice lady.”
A third begged: “I want June Brown as my chum, think how happy you’d be having her around.”
While a fourth posted: “She is brilliantly funny!’ and another said: “June is absolutely hilarious, what a funny woman!”
After the face treatment June decided to show off her Tibetan yoga skills to the group to demonstrate how she stays fit.
Resting her back on the floor, June was seen to lift her legs up off the ground, but ended up flashing her underwear to the group.
June explained: “You get onto the floor and you lay on your back.
“And then you lift those! Excuse me draws! Then you bring this head up towards those legs when they’re up.”
100 Years Younger in 21 Days continues next Tuesday on ITV at 9pm.
