Yes, Crystal Harris and Hugh Hefner have called off their wedding – but no, Dr. Phil’s son Jordan McGraw is not the reason behind the split.

These stories are “absolutely not true,” Harris’s manager Michael Blakey tells PEOPLE. “This is pure fabrication. There is no relationship, nor has there ever been one. This is a stupid rumor.”

Rumors of a romantic connection between the two first surfaced in March, when Harris and McGraw were reportedly spotted looking cozy at L.A. hotspot Chateau Marmont.

Blakey explains the only interactions Harris, 25, has had with McGraw have been strictly business. “They wrote a song together and that was the extent of their relationship,” he says.
