Molly Sims, Vivica A. Fox, Eve and Entertainment Tonight's Kevin Frazier dazzled on the blue carpet, as they turned out to support the La Vie En Blue gala fashion event for the Autism Speaks charity in Los Angeles on Thursday night.
ET caught up with Sims, who was co-hosting the event along with Frazier, before the event. The supermodel, who is pregnant with her third child, said being a mom brings the reality of autism diagnoses into focus.
"It's just now so prevalent that we have to really get in there and figure out the cause," the Las Vegas actress said.
"You never know, it can affect your family -- if not your family, someone who is close to you, someone in your family," she added. "I know there is not six degrees of separation anymore, there is one degree of separation. And I think it's hard being a mom because you just pray that everything is going to be OK, and when it's not you do really want to see how everyone will rally and come together and find information and research and hopefully we will find a cause.”
Even so, the 43-year-old said she was looking forward to growing her "tribe" with the arrival of her third child.
"We are going to be like a little tribe, you know. This was a little bit of an unexpected present -- that happened a little unexpectedly, but we are so happy," she said. Sims has two children already with her husband of five years, film producer Scott Stuber -- a son, Brooks, born in 2012, and an 18-month-old daughter, Scarlett.
The night's other co-host, Frazier, also opened up about how being a parent highlighted the importance of autism research. "It's important to support this," he told ET. "We have boys and boys are five times more likely to… be born with autism. So it's very important to support."
The Insider co-host, Keltie Knight, was one of the event's celebrity guest models and Frazier said he planned to give her a few words of wisdom. "I'm going to tell her to calm down and relax, you know, and be easy," he said. "I can't wait. She's all excited and it's going to be a trip. Keltie Knight on the runway. You better handle your business."
ET was a presenting sponsor of the high-fashion event, which featured a performance from Cirque du Soleil's Zumanity and a runway walked by celebrity guest models including Fox, who looked amazing in a bead-encrusted royal blue velvet gown, and actress Eve in a curve-hugging, lace-up dress.
The Autism Speaks gala was held to raise funds to support the nonprofit's mission of funding biomedical research into autism and its effects, and raising awareness of its cause.
