KSI went wild backstage as he watched little brother Deji grab his first ever boxing win.
The 25-year-old went into his 02 bout against fellow YouTuber Fousey having lost his previous three fights.
But he put that slump to bed, comfortably seeing off the American in brutal style.
Having already dropped Fousey with a jab, Deji ended the fight in round three by rocking his opponent with a big left – prompting the towel to be thrown in.
Watching backstage was headline act and big brother KSI, who had already defeated rapper Swarmz in his first fight of the night.
The 29-year-old had tipped his little brother to lose before the fight, so might have been pleasantly surprised as he watched Deji dominate.
