Good looks obviously ran in the family at the intimate book party hosted by Bill Guthy and Greg Renker in West Hollywood on Friday night. To celebrate Cindy Crawford's new tome Becoming, the supermodel arrived with husband Rande Gerber and gorgeous kids Kaia and Presley.

With a plethora of images to choose from, you'd think Crawford had it easy taking her pick of the litter for the beautiful publication. But actually Crawford took some convincing, she told us.

Clad in a flattering Antonio Berardi outfit, Crawford shared that the book ended up being an apt celebration for turning 50 recently—50 iconic images are paired with essays. "There were certain things that I wanted to talk about like things that I'd either talked to my kids about or I would want to talk to my kids about or my friends about," Crawford said. For one, "like people see nude pictures about me and they might make assumptions about what it felt like or didn't feel like or why I did it," she explained. "And I wanted to say, here's my stance on nudity. Or here's how I felt about body image or aging or becoming a mother."

Crawford also pointed out that it's not just about makeup or workout tips. "I couldn't be less interested in writing about that," she said. Instead, she wanted "to help people understand the art of photography and modeling. There's a skill involved. It's not just about being pretty."

Speaking of pretty, the crowd wasn't too shabby either. Guests sipped on champagne and a Casamigos Tequila specialty drink “Tipsy Jalapeno”, a spicy margarita and noshed on a cheese and charcuterie assortment, while Gerber and Crawford made sure all guests felt welcome. Maria Shriver arrived late in the evening, as did Lisa Rinna and Harry Hamlin who was sporting bright white hair. Meanwhile, David Foster stepped out after his divorce announcement and stayed close to some gorgeous leggy blondes—that is, his daughters Sara and Erin.

The highlight of the night, though, was likely when fellow supermodel Tyra Banks arrived just so show her support. The two gabbed enthusiastically before Tyra darted out the door again.

And even though both supermodels looked stunning, Crawford admitted her feelings on the aging process. "It's daunting," she said. "I think that was part of the process of doing a book for me was just embracing the good stuff, the wisdom, the experience."

Although she also has a sense of humor about the whole thing. "I was doing an interview the other day and I'm like, you know, one of the great things about getting older is you're more comfortable in your own skin. And then, I was like, maybe because it's a bit looser!"
