Olly Murs wrote on Instagram: “Oops sorry babe you asked me to do the challenge.”
The pair were filming a TikTok video where participants are challenged to lower their partners over water before lifting them up before they touch the surface.
Amelia later jokingly commented: “Remind me NOT to ask you do a TikTok challenge ever again.”
Michelle Keegan and John Terry were among celebs to comments, with Our Girl actress Michelle writing: “Oh my god!!!! I would of killed you!!!!” while stylist Lou Teasdale added: “Omg fuming”.
One fan wrote: “This girl deserves some serious treats after lockdown!” while others left laughing emojis at Olly’s brutal prank.
The pair are living together amid the coronavirus lockdown and the star previously admitted boredom was getting to him.
In one video shared days prior, Amelia could be heard screaming “for f***s sake!” after Olly pulled down his trousers and farted on her before running away.
He rapped “bored in the house and I’m in the house bored…” before he strutted into their bedroom, turned around, and let one loose as Amelia sat on the bed looking at her phone.
She quickly hopped off the bed and sprinted after The Voice UK judge. But Olly told them in a hashtag beneath the TikTok challenge: “NOT DUMPED YET.”
Olly has been feeling extra energetic in self-isolation and even showed fans his huge bulge in his white pants.
Dancing in his bedroom – he confessed his girlfriend could kick him out after waking her up early.
The singer was in high spirits on Saturday and refused to allow Amelia to snooze.
Showing off his incredible weight loss, the star put on Get Up by Byron Stingily, then danced around his bedroom.
Olly jumped on the bed, jigged and even swung from the roof beams
In the background, his tired girlfriend let out a light moan.
He captioned the video: “I think I’ll be dumped by the end of self-isolation.”
