The actress, 60, and her husband, Alan Hamel, were not at home at the time.
Somers said in a statement: "My nature is to look at the glass half-full. I don't have a son or daughter in Iraq. I haven't lost a loved one. We will rebuild, and I truly believe we will learn something great from this experience."
Actor John Cusack's house was also in the area near the fire, according to John Hildebrand, a local photographer who witnessed the star trying to save his home and a neighbor's.
"He basically came out of his house and had a hose on his property and was trying to spray the front of his house and the driveway," Hildebrand told PEOPLE. "It looked like he was also trying to spray the neighbor's house because they weren't home."
A spokeswoman for Cusack tells PEOPLE he's "fine" in the wake of the fire.
In addition, a spokesperson for actress Victoria Principal also confirmed that the home of the former Dallas star had been endangered, but was not harmed.
In all, some 20 acres had burned before the fire was contained by 300 firefighters, who "finally declared the fire out at 5 a.m.," Malibu Mayor Ken Kearsley said. "What's left is the disaster of these people's homes."
Although Malibu is home to Paul Newman, Mel Gibson, Pierce Brosnan, Pamela Anderson, Barbra Streisand and Courteney Cox-Arquette, among others, "This fire didn't just affect movie stars, it's affected the people who have lived out here for years," the mayor said, adding that an unidentified 94-year-old resident had died from smoke inhalation.
As for the cause of the fire, "Right now we cannot speculate about how this happened," inspector Rick Dominguez told the Associated Press early Tuesday.
