 The Playboy boss, 84, proposed to the 24-year-old aspiring singer while they were opening presents at the Mansion. The ring was in a Little Mermaid music box. Hef wound it up and had Crystal open it. He didn't say, "Will you marry me?" Instead, he said, "I hope it fits." (FYI: It didn't. It was a little too big but it has been resized and she is wearing it now.) 
 
 Crystal says she knew it was coming because they had talked about getting married. She even designed the ring with Hef's longtime secretary Mary O'Connor. "I picked out the diamond with Mary," Crystal said. "It all happened so fast and we're happy. Nothing's changed. Everything is the same." 
 
 It's a round diamond, a little over three karats and is on a platinum setting with diamonds that go around the whole band. Crystal tweeted a pic of the ring last night. 
 
 They are hoping for a summer wedding. She wants something small and intimate with "close friends and family." Crystal wants to design her own dress. And, yes, the big day will take place at the Mansion. 
 
 Crystal also says they have no plans to start a family. "I've never really been the wanting children type," Crystal said. "I just have a bunch of different projects I'm working on and that's fun for me so that's what I'm going to do." 
 
 As for family reaction, she said, "Both my parents are super supportive of everything and whatever makes Hef and I happy makes them happy. I couldn't be happier." 
 
 What about a prenup? "Whatever Hef wants me to do," Crystal said. "I'm happy. I have the singing thing going for me and other things so whatever he wants. I don't know anything about that stuff. I don't care. Whatever." 
 
 Bridget Marquardt sent the happy couple a box of Sprinkles cupcakes to toast the big news. Kendra Wilkinson-Baskett tweeted her congratulations. As for Holly Madison, she seems okay with the engagement, too. "Holly is coming to the Mansion on Wednesday to film a segment for her show, so it will be nice to see her," Crystal said. "I love all three of them. They're so sweet to me. They're all good girls." ||||| Hugh Hefner's Bride-To-Be, Crystal Harris, Flashes Her Diamond on Twitter

 "For those of you asking to see it here it is....My engagement ring from my love @ Hugh Hefner," Harris tweeted. 
 
 
 
 She then posted a close-up of the whopper ring, which needs no enhancement. It appears to be a multicarat round, brilliant-cut diamond set in a platinum band with smaller-diamond accents.

– The story of Hugh Hefner’s Christmas Eve proposal to 60-years-younger galpal Crystal Harris just keeps getting more and more romantic. Turns out he didn’t actually ask her to marry him, he just handed her a Little Mermaid music box (yep, really) that was holding the ring, and said, “I hope it fits.” It actually ended up being too big, Harris tells E!, but fortunately she can wear the symbol of their not-at-all-creepy love now that it’s been resized. Making the story ever more swoony: Harris wasn’t even surprised, having designed the ring herself after picking out the diamond … with Hef’s secretary. Click to see a picture of Harris’s rock.
