JLS and Olly Murs have been good friends since touring the country together last year.
But the Xtra Factor presenter, 28, could be forgiven for feeling slightly annoyed with the band after they played a terrifying prank on him on Tuesday.
The Essex solo singer thought he was responsible as bandmember Aston Merrygold, 24, appeared to be 'injured' following a human cannonball accident.
Oh my God! Olly Murs is horrified after watching 'Aston Merrygold' overshoot the landing mat in a human cannonball stunt
Daredevil: 'Aston' climbs into the cannon
Filming a segment for Channel 4 and
Cancer Research fundraiser Stand Up To Cancer, Olly was interviewing the
four-piece at SportHouse in Dagenham.
To raise money for the cause, Aston volunteered to be shot out of the cannon, with Olly being chosen to press the 'go' button.
Watched by hundreds of young fans, Olly pressed the button and found there was no action, so ended up pressing it a second time.

Off he goes… uh oh! Olly presses the button to shoot the cannon… and it isn't long before he is looking concerned
To the horror of Olly and his fellow onlookers, 'Aston' went flying out of the cannon and overshot the crash mat, crash-landing on a hard, wooden stage.
For two minutes, 'Aston' – who was actually a stuntman – lay still as paramedics rushed to his aid.
Olly appeared completely horrified and beside himself with worry as he wondered what had happened to his friend and if he was responsible because he pressed the button so hard.
You're alive! Olly looks relieved to find out it's all a prank
My poor heart! Olly admits the prank terrified him
Finally, the real Aston emerged to greet Olly and was completely healthy, to the singer's relief.
Following his scare, Olly tweeted the band: 'Still recovering, still shaking & still shocked!! @JLSOfficial you got me proper today!!'
JLS bandmember Marvin Humes wrote on Twitter: 'Just did an amazing prank with @ollyofficial and lots of JLSters!! Absolutely hilarious! Can't wait for u all to see!! Marv.'
Meanwhile, Olly is preparing to release his new single Troublemaker, which also features U.S. rapper Flo Rida from his forthcoming third album Right Place, Right Time.
