Contestant Robert White was SHOVED by Big Narstie after trying to dance with him on Britain's Got More Talent.
The comedian, who made it through to Sunday's live Britain's Got Talent final, was celebrating his victory on the spin-off show when things got a little nasty.
As Anne-Marie performed on the ITV2 show, hosted by Stephen Mulhern, 41-year-old Robert, who has Asperger's Syndrome, jokingly tried to dance with Big Narstie, grabbing hold of his wrist.
The rapper clearly had no interest though, and looked at the comedian before shoving him away with both hands, sending Robert flying backwards and out of the shot.
The move made host Stephen pull an awkward face, but thankfully Robert wasn't too upset about it.
He later took to Twitter to say they'd made up afterwards.
He said: "Big Narstie hi-fived, shook and then made up. No bad feelings from me. To me the visual joke was obvious; the tiny guy dancing with the big guy, but not everyone thinks in comedy, so I think you should give the benefit of the doubt"
Big Narstie re-tweeted Robert's post and replied saying: "my g all love f*****g smash da final"
However, viewers weren't impressed by the rapper's actions and called on boss Simon to never have him back on the talent show.
One said: "Dear @SimonCowell I suggest @bignarstie is never booked again for a show under your name. He just aggressively pushed Robert White live on BGMT when Rob tried to dance, absolutely disgusting behaviour, from an ignorant vile bully"
Another wrote: "Cant believe what I have just seen on BGMT. Can only be described as 'Big Narstie' violently and aggressively pushing Robert White"
While one said: "Wtf did I just see at the end of Britain's Got More Talent?!!! Big Nasty just pushing Robert White away !!! Living up to his name"
And another commented: "Did I just see Big Narstie aggressively shove Robert White? It didn't look remotely in jest. Was it just me?"
Robert later took to Twitter to thank people for their support during the semi-final.
He said: "Dear All, thank you for the nice messages and tweets. I literally can't reply to them all because my phone has gone into meltdown more than that time I opened up Grindr whilst watching a performance off 'sing-along The Sound of Music'. But to everyone deepest thanks !!!!"
He'd taken sly swipes at each of the judges during his semi-final performance with his comedy song, telling David Walliams he was obsessed with his "heterosexual pretending" and Amanda Holden that she was obsessed with "trying to look young like she used to".
He also cheekily suggested Alesha Dixon was obsessed with "dressing like a [hooker]" and that the thing Simon Cowell loves the most about Britain's Got Talent is his own voice.
* Britain's Got Talent continues tonight at 7.30pm on ITV
