Lee Nelson was DENIED access to the third Britain's Got Talent 2016 semi-final on Tuesday after turning up wearing a BURKA, it's claimed.
According to The Sun, the prankster comedian - real name Simon Brodkin - attempted to enter the studio as an audience member while dressed in a burka and pushing a wheelchair, accompanied by an unknown woman pretending to be his daughter.
However, security at the show's studios in Wembley, London was tightened further after judge Amanda Holden was caught up in a police chase the previous night - and Simon was turned away after one guard saw through his disguise.
"Audience services were on high alert after the drama so were not taking any chances," a source told the newspaper.
"One of the staff clocked Simon and flagged it to their boss who instantly smelt a rat. He was refused entry and sent on his way."
Simon's latest stunt came after he AUDITIONED for the current series of Britain's Got Talent as a rapping rabbi - and won four yesses from the judges.
It wasn't until after he left the stage that a staff member realised who he was and alerted the producers. Footage of his audition did not air on the show.
Simon formerly appeared as Lee Nelson in BBC Three's Well Good Show - although he is now better known for his ambitious high-profile stunts.
In 2014 he invaded the stage during an X Factor live show pretending to be the ninth member of Stereo Kicks - and in 2015 he made international headlines by showering controversial football bigwig Sepp Blatter with wads of fake cash at a FIFA press conference.
