"I met Charlie back in the mid to late 90`s and I spent a lot of time with him," porn star Tabitha Stevens told RadarOnline.com."He is one of the most caring, genuine, nicest guys I think I`ve met in my entire life." Stevens, 40, admitted to RadarOnline.com that she was initially paid to spend time with Sheen, but that eventually the two developed a friendship.
