Hef & Crystal Harris Reveal Wedding Plans

In their first interview since becoming engaged, Playboy founder Hugh Hefner and his gorgeous Playmate fiancee Crystal Harris spoke exclusively to Radar Online about the proposal and revealed that the ring didn’t fit!

"It couldn't have happened in a more loving way," Hef, 84, said about the Christmas Eve proposal.

Crystal said she knew she was getting a ring because one of Hef’s staffers helped her figure out what kind of diamond she wanted, but she was still surprised when he finally presented it to her.

"I love the Little Mermaid and Hef gave me a Little Mermaid music box and he wound it up and when I opened it the ring was in a box inside. I cried!"

"There was no down on one knee; we don’t follow traditions like that. When I opened the box Hef said ‘I hope it fits,’ but it was too big! I had to get it re-sized!"

The happy pair hasn’t set a date yet but Hef told Radar Online that the wedding might become a reality show.

"The wedding will definitely be at the Mansion," Crystal revealed. As for her dress? "I would love to design my own dress."

Hefner told Radar Online that he isn't going to go wild before the wedding, but admitted that he has had a charmed life. "I've been having my bachelor party for the last 50 years."

Crystal said that they have the full support of his children. "I love Hef’s sons, they’re great and they’re really happy about the engagement."

According to Crystal, she and Hef aren’t planning to have any children. "I’ve always said I don’t want kids, just animals and there are plenty around here."

Crystal mused on what she loves most about her new fiancé. "He is the nicest person I’ve ever met in my whole life. He is one of the best influences on me and I love him."

Hef spoke fondly about Crystal. "Her personality and her character are what I love. She's very upbeat and a loving person and doesn't tend to have moods. She is always looking on the bright side. She's not petty, she has good character and is down to earth.

"This is the final act for me and the best," Hef said about his engagement and upcoming marriage to Crystal.

Christina Aguilera's Is Not Engaged To New Man

Christina Aguilera's new boyfriend put a ring on it, but don't get the wrong idea.

Matt Rutler "gave [a ring] to her for her birthday," a source tells PEOPLE. "It's not an engagement ring and they're not engaged. It was a surprise gift from him."

Although the lovebirds aren't necessarily saying "I do" anytime soon, they are getting more serious. Rutler's mom has had the honor of meeting Aguilera. And Rutler was by Aguilera's side at her New Year's Eve bash, which was attended by her own mother, brother and sister.

Aguilera recently introduced Rutler to her son Max when she brought him to the Peterson Automotive Museum.

"Christina took Max on the fun outing so he could bond with Matt," a source says. "Max was initially a bit shy, but later warmed up to Matt. It seems very important to Christina that Max got along with Matt."

The source also says Rutler has been spending the majority of his time staying at Aguilera's Beverly Hills home, while the singer's ex, Jordan Bratman, is now living in a rental home nearby.

Crystal Harris, Hugh Hefner Talk Wedding Plans

Hugh Hefner and his fiancée Crystal Harris welcome ET's Kevin Frazier into the Playboy Mansion for the dish on their wedding, their 60-year-age gap, and whether or not they plan on having kids!

Hugh and Crystal tell Kevin they're eyeing a summer wedding at the Mansion, an "intimate" ceremony with close friends and family -- "no big, blow-out affair," Hef says.

"Giving it another chance after a couple of failed marriages is an adventure, but it's something that I'm committed to," the Playboy mogul says.

But what about that big age gap between 84-year-old Hef and 24-year-old Crystal? Is it problematic? "I don't notice the age difference with Hef at all," Crystal says. "If anything I have to keep up with him."

Speaking of keeping up, Kevin's gotta wonder: Is Hugh still sexually active? "I'm doing my best. Dancin' as fast as I can," the energetic 80-something says with a smile.

Which begs the question: Does Hef want more children? "Well, we'll see. That's not part of the big plan," he says.

One thing that's not in question: Hef's love for his Playmate bride-to-be. "She's a beautiful human being inside and out; a woman with real character and humor," he says. "We're really devoted to each other. I think that the relationship is the center of both our lives."

Hef & Crystal Harris: Inside Their Engagement

It wasn't just that Hugh Hefner presented Crystal Harris with an engagement ring on Christmas Eve – it was how he did it that impressed her.

"We were up in the bedroom," Harris, 24, tells PEOPLE, "and my favorite movie is The Little Mermaid, so he had the ring in a Little Mermaid box, and that was so special. I opened it and the first thing he said to me was, 'I hope it fits!' "

Adds Hefner, 84, "I got her a little music box with the Mermaid theme to it, and it just looked like the perfect size and the perfect place to be the ring box. So when she started unwrapping that gift, I reached over and wound it so it was playing music while she discovered what was inside."

Although she cried with happiness, Harris says, "There wasn't any 'down-on-one-knee' or anything like that, because we are not traditional."

The ring is a circle diamond "a little over three karats," says Harris, "and it's on platinum setting and it has diamonds all around the band as well. It's so pretty."
