His vindictive former fiancée, Crystal Harris, may be throwing stones, but a bevy of Hugh Hefner’s other blond beauties have his back. Bridget Marquardt, who starred with Holly Madison and Kendra Wilkinson as Hef’s trio of peppy girlfriends on The Girls Next Door until they all parted ways in 2008, calls Crystal’s recent actions “unfortunate.” “You need to have a certain level of maturity and respect to keep things quiet,” Bridget, who is the new face — and smoking hot body — of Durex’s Get a Room campaign, tells In Touch. “There is just no excuse for all of that. It’s so unfortunate.”

Unlike Crystal — who left her heartbroken fiancé just days before their planned wedding amidst rumors of an affair with Dr. Phil’s son, Jordan McGraw, and then bashed sex with Hef to Howard Stern — Bridget remains close friends with the Playboy mogul. “He’s great, and he has a whole new lineup of girls!” Bridget says of Hef’s new leading ladies, Anna Sophia Berglund and Shera Bechard. “I met them last weekend. Hopefully, he’s making the right decisions!”

As for Bridget, she’s moving on just fine with her boyfriend of three years, Nick Carpenter, and a new career move as a costume designer. “I designed them all, and they’re just coming out in stores. It’s going to be worldwide!” she says of her debut Halloween line. And the sexy pinup seems to be the perfect spokeswoman for Durex’s new program. “It’s taking people who are in love and have an amazing relationship, and encouraging them to have the freedom to spice it up a little bit!” she explains.
