Jarvis Kaye is a 17-year-old professional video game player living in a $21 million Hollywood Hills mansion.

The teenager is one of many youngsters making a fortune from playing Fortnite at a professional level.

But this life could all soon be a distant memory.

The professional gamer, known online as FaZe Jarvis, was this week handed a life ban from playing Fortnite after being caught cheating.

He had allegedly been using "aimbot" software - a bot which shoots and kills rival players automatically - to unfairly win matches of the popular game.

Jarvis broke down in a video when explaining his life ban to his two million YouTube followers, saying he had only activated aimbots for instructional videos and never in competitions.

"I'm going to take accountability for my actions and I understand completely why this has happened, I just wish I had known how severe the consequences were at the time and I never would thought about doing it. I love all you who still support me, this is not the end," he said in a statement.

The gamer had moved from the small Surrey village of Oxted to the multi-storey Hollywood Hills mansion earlier this year after joining an e-sports team known as the "FaZe clan".

In a YouTube video, he gave a tour of theso-called "FaZe House", which comes complete with 10 bedrooms, a private cinema, gym and stripper pole.

The mansion overlooks Los Angeles and also has a private pool on the upper deck.

It's unclear if Jarvis will be able to stay at the house after Epic Games stood strong on its ban.

"We have a zero-tolerance policy for the usage of cheat software. When people use aimbots or other cheat technologies to gain an unfair advantage, they ruin games for people who are playing fairly," Epic Games said in a statement.

Fortnite is making $300 million every month. (A Current Affair)
