A controversial X Factor contestant was stunned into silence after having her microphone ripped from her hand during a surprise stage invasion.
Honey G had just finished performing MC Hammer's U Can't Touch during the latest season of The X Factor UK and was being assessed by judges when the incident happened.
Several people stormed the stage and were removed by security.
"There was a stage invasion by four men, with one further person in support. All five had been in the audience," NME.com reported a spokesperson as saying.
"They were spoken to by police and security and have now been removed from the studio."
NME reported the pranksters were later outed as Trollstation, known for live pranks including football pitch invasions and faking an art heist.
Honey G, a 35-year-old rapper from Harrow in North-West London whose real name is Anna Georgette Gilford, has attracted controversy for her performances of hip-hop classics.
She's been branded a racist and "a white lady that dresses up in Ali G" clothes by prominent musicians.
Gilford has defended her style, telling chat show This Morning that, "Any allegations of me being racist are completely false.
"All that stuff to do with me attacking black culture is utterly ridiculous. I've never said anything racist or behaved in that way. Just because I'm pushing music from a black origin doesn't mean I'm attacking black culture.
"They are using the race card against me. I feel like they are discriminating against me because I am white. I'm not the only white person in the world who likes black music.
"There's no evidence, proof or truth that I am a racist."
