BRITAIN’S Got Talent viewers were left cringing at KSI after he failed to see the funny side of one of the acts.

Musician REN DMC took to the stage to perform a very personal rap roast aimed at each of the judges.

In the routine, the battle MC delivered a savage set of bars that took aim at Alesha Dixon’s career, and KSI’s music “hits”.

The rap took a blowtorch to the judging panel, leaving in absolute stitches.

However, KSI didn’t look impressed and buzzed the rap star.

The rapper took a brutal swipe at the star’s famous hairline and his music career.

The crowd gasped as he spat: “I heard that you do boxing now… I know why you hit your opponents, because you can’t make a hit in your music.”

He finished the demolition job by branding the Prime mogul “the worst thing in rap since Ant and Dec”.

While KSI sat there stony faced, big boss Simon was doubled over in hysterics, loving every second of his colleagues being taken down a peg.

Fans were quick to give their take online, with one sharing: “KSI is such a wet wipe, get him off #BGT.”

Another wrote: “Bro roasted KSI” followed by three laughing emojis.

“So KSI can’t take a roasting,” said a third, while another added: “KSI couldn’t take it though.”

Following the audition, KSI sounded like he was ready to lace up the gloves for a digital scrap.

He shared: “Oh, you know what? I give it to him. He smashed it.

“When he was just cooking me, cooking my forehead, I was there like, ‘all right, this guy’s going nuts’.

“But to do that in front of thousands of people in the theatre and also the millions watching on TV and online, it takes a lot of balls.

“He was very good. It was very funny and I appreciate it. I don’t take myself too seriously. So stuff like that is always great.

“The danger for him though is I’ve got a huge platform online, I can get him back tenfold online.”

Opening the set, the rapper turned his sights on Alesha. While he started with a compliment, comparing her to Alicia Keys, he then quipped:

“I used to watch you on the TV. Pretty nice girls, but still the Temu version of Spice Girls.”

Even Amanda Holden wasn’t safe.

The rapper joked that after listening to her on the radio, he found her words so “inspiring” that he “turned it off and drove in silence.”
