Hugh Hefner and Crystal Harris: Is she cheating on him with Dr Phil's son?

http://www.nma.tv/ Playboy founder Hugh Heffner is surrounded by women. But 24-year-old Crystal Harris managed to catch the octogenarian's eye. Hef proposed to Harris last year. Yet Harris appears to be stepping out on Hef. The bunny reportedly has eyes for Jordan McGraw, the producer of her debut album Harris and McGraw were seen getting lovey dovey with each other at an LA hotel bar. Is McGraw cock-blocking the legendary womanizer Hugh Hefner? Heffner and Harris were set to wed on June 18. Perhaps they can work their problems out before the big day with Dr Phil, who also happens to be McGraw's father.
