JLS star Aston Merrygold had fans screaming as he dropped to his knees and offered to suck a man's toes for a new TV show.
The singer was a special guest on Channel 4's Tapped Out Prank Stars, which sees celebs tasked with cringeworthy feats by show hosts Nella Rose and Harry Pinero.
The hosts secretly pull the strings, telling their guests what to say via hidden earpieces.
Good sport Aston was faced with an intimate crowd as he gave a fake life-coaching leadership presentation in a dimly lit room for his challenge.
He told the audience: "Enough of the foreplay. Celebs have actually been manipulating you. Now, they're even selling feet pictures. So that's actually an avenue I'm looking to go down.
"Everybody, take out your phones."

It left the hosts' jaws wide open and studio guests ArrDee and Fatiha El-Ghorri in shock.
Aston then beckoned a man in the audience to join him at the front.
He shook his hand but didn't let go and looked him dead in the eye as he said: "Can I suck your toes?"
