Naomi has some many major issues, in my opinion. One of them is she doesn't like to see other models of color, namely Jessica to flourish the business. Naomi has, "There is only room for one at the top" phobia. Even Tyra Banks had her run in with Naomi and her issues. Poor Jessica.
I don't believe for one second that Naomi Campbell has anything against Jessica. Maybe she had her little thing with Tyra Banks 100 years ago but Jourdan Dunn who was being touted as 'the new Naomi' said that Naomi was really friendly towards her and invited her to lunch. She did not clobber her with a blackberry. So i think its important not to base anything on media speculations
