The wedding's back on – though it may be a good idea to save that gift receipt.
Hugh Hefner, 86, officially confirms that he is once again engaged to Crystal Harris, 26, telling his Twitter followers, "I've given Crystal Harris a ring. I love the girl."
And to prove it, Harris posted photos of the big diamond sparkler, calling it "my beautiful ring."
Neither announced a wedding date, though sources tell PEOPLE they're planning to tie the knot at the Playboy Mansion in Los Angeles on New Year's Eve.
Whether that still happens remains to be seen.
