The party continued into New Year's Day for Hugh Hefner and his new bride Crystal Harris, who celebrated their New Year's Eve wedding with a big bash at Hef's legendary Playboy Mansion.
Celebrity guests included Gene Simmons and his wife Shannon Tweed (who herself was 1982's Playmate of the Year), who didn't miss an opportunity to kid with the 86-year-old magazine mogul.

"We wish you the best .. what are you doing tonight?," Gene suggestively joked.
"It's about time ... I'm just kidding," Shannon added.
Hefner tied the knot with his 26-year-old model girlfriend Monday at the Playboy Mansion in Los Angeles, their second attempt at tying the knot -- Harris was nicknamed "Runaway Bride" for calling off the couple's wedding just days before the ceremony in June of 2011.
