Britain's Got Talent: Simon Cowell pranked by Belfast free-runner Matt McCreary
It is Simon Cowell's turn to fall for a Britain's Got Talent prank tonight when a fearless free-runner pretends to be injured after plunging from a balcony during a terrifying routine.
Cowell, who earlier in the week conned Amanda Holden into thinking she was being dumped from the show for Cheryl Fernandez-Versini, was left open-mouthed when 20-year-old Matt McCreary, from Belfast, leapt around the stage.
Viewers tuning in to tonight's show will see Cowell ask McCreary: "Oh my God, Matt are you really ok?" as he lies on the theatre floor after diving from a balcony.
The 20-year-old, who also leaps over show hosts Ant and Dec on stage, also impressed Amanda Holden, who told him: "We have never seen anything as brave and dangerous before".
But not everyone on the panel was won over, with David Walliams joking: "Jumping over two people who are that short isn't really such a big deal."
The "Do Not Try This At Home" warning also flashes up for another act - brother and sister roller-skaters Billy and Emily England.
The pair, from Birmingham, stun the audience with their routine and impress Alesha Dixon who calls them "fearless".
Other acts in the new series of the ITV talent show include Magdalena Stilova,a 56-year-old contortionist from Bulgaria, and Parisian Marc Metral whose singing dog, Wendy, so impresses Cowell he phones his girlfriend Lauren Silverman to tell her about it.
