Hugh Hefner wants to stay with Crystal Harris until he dies.
The 86-year-old Playboy founder said he doesn't care about the 60-year age difference between him and his 26-year-old fiancee and is sure she is the right person for him.
He tweeted: "The dramatic age difference between difference & Crystal & me really doesn't matter. Whatever time I have left, we want to spend together."
As an early Christmas treat, Hugh managed to secure Crystal membership to the exclusive Club 33 at Disneyland in Anaheim, California.
He tweeted: "Crystal became a member of Club 33 at Disneyland today. A Christmas gift to my darling that we can share together."
In response, Crystal simply tweeted: "Happiness is limitless."
Hugh - who has been married twice previously, to Mildred Williams from 1949 to 1959 and Kimberley Conrad 1989 to 2010 - and Crystal recently reunited after she initially called off their engagement just days before their wedding in June 2011.
They are now planning to tie the knot again on New Year's Eve (31.12.12) and the former Playboy Playmate of the Month has been flashing a huge new diamond engagement ring. She has also changed her Twitter handle to Crystal Hefner.
Speaking of why she broke off the engagement, Crystal previously said: "I got cold feet. Over time I just realised it wasn't for me, it was all happening so fast.
"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."
