It's all over for Nicky Hilton and David Katzenberg. Due to conflicting, hectic schedules, the couple has split after four years of dating, insiders confirm to The New York Post.
"The main reason was that they have been busy with their work, and it has made it difficult to spend time together," a source tells the newspaper. "Nicky has been back and forth traveling overseas a lot with her business. She has recently been in Asia promoting her jewelry line, and David is starting a new production company."
Katzenberg created MTV's The Hard Times of RJ Berger, while Nicky actually does seem involved in the family business. She'll be leaning on one of those family members in the face of this break up.
"Paris and I are going to go to the South of France next week for some business and pleasure," Nicky told Us Weekly on Wednesday.
