Hugh Hefner's 24-year-old fiancee, Crystal Harris, might not be ready for monogamous matrimony with her 84-year-old beau after all. Life & Stylewrites that Harris has been cavorting with Dr. Phil McGraw's son Jordan. In all honesty, Hefner has got to be a real loser spending monies on whores that will never even really like a senior citizen like him.

The magazine reports witnessing the "lovebirds cozy up at the Chateau Marmont in LA on March 14. While Crystal was hoping to keep their romance low-key, Jordan didn't care to hide his affections, kissing her shoulder and trying to hold her hand -- still adorned with her 6-carat engagement ring."

Jordan is Dr. Phil's younger of two sons. The older, Jay, is married to Playboy model Erica Dahm.
