Playboy mogul HUGH HEFNER is engaged (again) to CRYSTAL HARRIS (again) and the two will walk down the aisle at the Playboy Mansion on New Year's Eve - according to TMZ.

Harris played the part of “run-a-way bride” on wedding #1 in June 2011 ... just five days before the big day.

Wedding bells rang for Extra and X Factor co-host MARIO LOPEZ and girlfriend of four years COURTNEY MAZZA Dec. 1 in a Mexican beach wedding, US Weekly has exclusively confirmed.
