Nicky Hilton and David Katzenberg Split

Hilton heiress, Nicky Hilton and long-time boyfriend, David Katzenberg, have called it quits. The couple has dated for the last four years but blames busy schedules as the reason for their demise.
Sources from the New York Post are confirming the break-up saying, “They broke up quietly after four years together. The main reason was that they have been busy with their work schedules, and it has made it difficult to spend time together. 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. Their schedules never seemed to match.”
