Model Naomi Campbell reportedly made some guests, who attended her 45th birthday party, make a donation to her charity for the privilege of getting on the guest list. The supermodel celebrated her birthday with a star-studded bash at 15-bedroom castle Chateau Saint Jeannet, located just outside of Nice in the South of France. Names like Leonardo DiCaprio, model Gigi Hadid, Mary J. Blige and Kendall Jenner were present. It has now been revealed that Campbell charged some non-celebrity guests up to $1,800 to enter the event on May 23. "People paid to get on the guest list... Naomi wanted to capitalise on the prestigious group of people that were at the (Cannes International) Film Festival," an insider told nydailynews.com. Although there were several stars in attendance, many who paid to join the party were reportedly underwhelmed by the celebrity turnout and by the fact that Campbell didn't arrive until after midnight, despite proceedings starting at 9 p.m. The source added: "A lot of the billionaires were a bit upset because she didn't show up until midnight. Everyone else started arriving at 9 p.m." A representative for the supermodel confirmed that Campbell charged some guests, but has revealed that it was for a donation to her charity Fashion for Relief. The spokesperson said: "Some guests were invited to make a donation to support her charity, Fashion for Relief, in conjunction with their attendance at the event."
