Leo always wants to be in the center of attention and putting two Leos together is not a great idea. The two will most likely spend most of their efforts competing with each other. Both will want to be the one to lead, so a compromise has to be found if this relationship is to work. Leos are very loyal, warm and loving individuals, so in the unlikely case of this relationship working out, it will be pretty great. Generally it's a difficult challenge making this match work.
