The blonde beauty called off her marriage to the 85-year-old Playboy founder just days before it was due to take place last month, and has now admitted she started getting cold feet in the run up.
In a TV special 'Hef's Runaway Bride', Crystal says: "I never as a little kid imagined what my wedding would be like one day but I kind of knew that I wasn't supposed to be feeling like this," Crystal says during the clip.
