Nicky Hilton and David Katzenberg have reportedly parted ways after dating for four years.
According to The New York Post's Page Six, sources say the split was due to work schedules.
"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," a Page Six source claimed. "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."
Adding, "There is no scandal or any third person -- they remain close friends, they have been friends since they were teenagers."
Nicky, 27, and David, 28, reportedly talk regularly and often Tweet each other.
