86-year-old Hugh Hefner has reunited with his 26-year-old runaway bride, Crystal Harris, a year and a half after Harris got cold feet just before their first wedding. TMZ is reporting that the couple will finally take the trip down the aisle for a New Year's Eve wedding at the Playboy mansion.  Hefner and Harris have apparently worked out their issues since Crystal moved back into the mansion earlier this year. A source told the website that Crystal's time away taught her how to stand on her own two feet -- something she felt she needed to work on before marrying Hefner.  Sources are saying the wedding will be a gathering of close friends and family.  Radar online is reporting that Harris will be wearing the same gown she was planning to wear for their original wedding back in June 2011.
