Doctors love the company of a doctor and celebrities only love the company of their kind. Same is the case with rapper 50 cent who loves enjoying and partying with celebrities because he thinks that they make him feel normal.
50, who just announced his new production company said, "I get a chance to feel normal when they're (other celebrities) around. I watch people get intimidated by their celebrity opposed to mine at some points, and that's fun for me."
For the interview sake the “real” celebrities are easy to approach while these newcomers who have got the status of a star very early in their career turn into real big heads.
