Crystal and Hugh Hefner are "happier than ever".
The 27-year-old blonde model famously walked out on the Playboy founder just days before they were due to marry in June 2011 but they later reconciled as they "missed" each other and, after tying the knot on December 31 last year, she says their relationship is currently the best it's ever been.
She said: "I missed him and he missed me. We're happier than ever, things are better now than they were then.
"Hef loved me more than I've ever felt in my life."
Despite the 60-year age gap between them the 'Call the Cops' singer says she and her 87-year-old spouse get along "great" and have a lot of "fun" in their "romantic" life together.
Speaking on 'Access Hollywood Live', she said: "Hef's very romantic, very cozy. We really care about each other and get along great. I don't notice the age difference. Hef's a lot of fun."
Hugh is famous for dating several women at once but Crystal - his third wife - also insisted their marriage is "exclusive".
Crystal has previously admitted taking time away from her relationship with the media mogul made her appreciate what they had together.
She has said: "He believes in love. Hef loves me more than anybody else in a relationship ever has. It took me time away to realize that. I think I realised that here is where I'm meant to be."
