Hugh Hefner’s new twin sister girlfriends, Kristina Shannon and Karissa Shannon, were spotted at a medical cannabis store.

We assume the twins weren’t buying allergy medication, or birth control pills. Then again, maybe Hef has a medical condition we don’t know about yet.

Hugh Hefner already has twin girlfriend replacements Karissa Shannon and Kristina Shannon, but now he’s added another blonde. The new girlfriend is 22 year-old Crystal Harris. From her MySpace page she sounds like a bit of a romantic, which is exactly Hef’s type.

Kendra Wilkinson chimed in on Hef’s new girl saying:

"Hef will always be Hef. You can never change him. Hef will keep going on. He’ll keep loving women, keep loving the big boobs and blondes."

Indeed he will.

Hugh Hefner (82) posed for this picture with his nineteen year-old twin girlfriends Karissa Shannon and Kristina Shannon. The girls sported a painted on tribute to Hefner on their chests, and the picture was used on the official Christmas Card. Hefner has officially moved on.

Hugh Hefner talked the other day about how sad he is, that Holly Madison has decided to move on after Hugh made it clear they will never marry, or have children. Well Hugh has moved on as well.
