However, in the end, only one can win each of their hearts.
Simon posted his first group video in March 2014: a crossbar challenge with various other You Tubers.
Simon was born in Hemel Hempstead, a town in Hertfordshire, England. Simon attended Berkhamsted School, a private school in his local area which educates students from the age of 3 to 18.
It was here that he met KSI when they were both in secondary school.
The two hated each other initially and came into contact (literally) at the age of 12/13 when they had a physical fight in a class.
The teachers stepped in and attempted to force them into an unlikely friendship.
From JJ, Simon was inspired to create a channel of his own.
