Crystal Harris' Mrs. Hefner Playboy cover hits newsstands Friday

Most awkward magazine cover ever?

Crystal Harris, Hugh Hefner's former fiance, takes of the cover of the July issue of Playboy, which US Weekly debuted. Pretty nice wedding gift, huh? The headline reads: "America's Princess: Introducing Mrs. Crystal Hefner."

Yeah, that's pretty awkward.

The issue hits newsstands on Friday, the day before their wedding was set to take place. The photo shows Harris wearing some of Hefner's signature pieces -- his silk robe and captain's hat -- and is smoking his pipe. Their dog Charlie is also featured on the cover. Hefner recently tweeted, "Crystal took Charlie with her when she left & I really miss him."

Harris, 25, and Hefner, 85, called off their wedding on Tuesday, June 14, just five days before the wedding. Yesterday, Hefner confirmed the news on his Twitter account, tweeting, "The wedding is off. Crystal has had a change of heart.The breakup is a heart breaker, but better now than after the marriage."
