Hefner, 86, is planning to tie the knot with Harris at the Playboy Mansion on New Year's Eve, one and a half years after the 26-year-old ran away from their planned June 2011 wedding, reported TMZ online.
Harris ran off from the Playboy Mansion just five days before their big day last year. She then tried to pawn her engagement ring and fight the octogenarian for custody of their dog.
But according to sources, Harris and Hefner are better than ever these days, since the glamour model moved back into the Playboy Mansion earlier this year.
The couple have worked out all their previous problems and decided recently they want to try and get married again.
Harris feels the time she spent apart from Hefner really taught her how to be independent and stand on her own two feet... Something she felt she needed, sources said.
The wedding will be an intimate gathering with just close friends and family.
