Ant and Dec were convinced a viewer was going to flash them in excitement after she played the segment Win The Ads on Saturday Night Takeaway.
Fiona from York, who appeared by video link on the live family entertainment show, was clearly thrilled with her win.
At first she placed cardboard masks of Ant and Dec’s faces on her chest and she rose up on the couch and pulled at the bottom of her top.
“Leave it” said Dec, and Fiona mimed lifting her top.
“Don’t do that,” warned Ant.
As she continued cheering with excitement on the couch the hosts quickly cut away from the action.
“We’ll leave it there because this could get dangerous,” said Ant.
“I thought we were going to have that,” said Ant, making a lifting top motion.
“I thought that as well,” agreed Dec.
Viewers took to Twitter to comment on the scenes.
“Oh my goodness. Fiona rubbing Ant and Dec’s face on her t**s and then almost flashed the entire nation,” tweeted one viewer.
“Did she just try to lift her top up?” asked another.
“Thought she was gonna flash,” said another viewer.
“I’m enjoying @antanddec sweating a bit with the live videos,” said another fan.
“The whole nation just shouted ‘noooooooo’ at Fiona in pure panic,” said another.
Another SNT viewer called Fiona a ‘legend’ while others called for her to be brought back on the show.

“Fiona please give me your energy,” said one fan.
“Fiona on Ant And Dec was awesome,” said another.
“If everyone was as happy as Fiona, the world would be a better place,” another said.
Last week a guest on the same gameshow segment was branded an ‘icon’ on social media after she was told by Ant McPartlin and Declan Donnelly that she had won in the giveaway for viewers.
Her reaction was to rip her wig off in celebration before popping it back on.
