Los Angeles Hugh Hefner obtains marriage license

Sunshine Magazine

The couple recently rescheduled their wedding and will be tying the knot on New Year's Eve, almost a year and half after the aspiring singer left the Playboy mogul shocked when she called off their wedding just five days before they were due to marry in June 2011.

But a source told Sunshine Magazine that they are determined to spend the rest of their lives together and were seen at a courthouse in Beverly Hills on Tuesday morning where they filled in the necessary paperwork in order to make their upcoming ceremony legal.

The couple moved back in together in May after Crystal, 26, begged Hugh, 86, for forgiveness. They are now preparing to wed at the Playboy mansion in Los Angeles.

Cold feet

According to insiders, the couple has only invited close friends and family members to celebrate their special day later this month.

They are said to have completely resolved the problems, which previously led to the model getting "cold feet".

Speaking after she backed out of the wedding last year, Crystal explained she knew it wasn't the right step for her.

"I got cold feet. Over time I just realized it wasn't for me, it was all happening so fast," she said. "I actually spoke to Hef about it before I left and we both came to the decision that getting married wasn't the best for either of us."
