BRITAIN'S Got Talent judge KSI got his own back for brother Deji's shock prank on the reality TV series in epic fashion with a huge on-air scare.
The ITV panelist enlisted the help of Lorraine show worker Michelle to cause his sibling to collapse to the floor on Monday's live episode.
Over the weekend, fans watched as the ordinarily super-cool KSI, 31, was left rattled as he was tormented by a dark hooded figure during one eerie Britain's Got Talent audition.
KSI, who was standing in for head judge Simon Cowell, 65, was left disturbed when he was strapped by his hands to a chair as the mysterious person said how they could reveal the star's closest memories.
They then recalled a time from 31-year-old's past where a girl he fancied didn't like him back.
KSI was stunned as the creepy figure revealed how he had cried for days over his heartbreak - yet when Deji Olatunji, 28, was revealed as the man behind the mask, it all made sense.

Yet just when Deji appeared to have scooped the bragging rights over his sibling, KSI turned the tables on Monday's Lorraine.
The one hour show was presented by stand-in anchor Christine Lampard, 46, who chatted to YouTube star and boxer Deji about his antics.
He confessed: "My main goal was to prank my brother. I didn't want him to know it was me, so I tried to change my manner, the way I was walking, I was trying to change things around really."
He also let slip show bosses had told him to "make it loose" when he tied KSI in the chair, but after seeing him "edging off" he decided to make the bands tighter.

Deji also revealed the pair had a spat shortly prior to his audition - which added more fuel to his prank.
Yet after he admitted he had been "avoiding" the singer since Saturday's show, Deji was left squealing and tumbling off his seat when a clown burst out from backstage and shocked him from behind his chair.
He could only utter the words: "Oh my gosh!" as he kneeled on the floor in his green tracksuit.
Christine reached out to hold his hand and said: "I'm so sorry you know I wouldn't do that to you, would you like to hear what he has to say?"
A video of KSI then panned out on a huge screen behind the pair showing him cackling as he said: "Got you bro!
