Cindy Williams dishes to ET about her new tell-all, Shirley, I Jest!: A Storied Life, which covers everything from her time on Laverne & Shirley to her love life.
Cindy and her partner in crime, Penny Marshall, became television icons through their characters originated on Happy Days. Spinoffs in the '70s were rare, but for Cindy and Penny the decision seemed to be a no-brainer. Their sitcom Laverne & Shirley became the No. 1 show on TV in the late '70s and was nominated for six Golden Globe awards.

As Laverne & Shirley entered its eighth season, Cindy got pregnant and walked away from the show. The series ended soon after.
"They had me working on my due date, and they couldn't deal with it -- that I needed time off to have a child," Cindy told ET's Nancy O'Dell. "It just ended up I didn't do that season of the show."
Today, Cindy's relationship with Penny remains as strong as ever.
"We see each other all the time," Cindy said. "We watch TV together. She likes to watch television in the arctic, so she actually has jackets in her room."

In her book, Cindy also dishes on her romantic relationship with the late comedian Andy Kaufman.
"I just adored him," Cindy said. "From the moment I laid eyes on him on Saturday Night Live I just thought, 'What a huge talent!' He just made me laugh."
Cindy famously appeared on Andy's ABC special, Andy's Funhouse, and it became one of the most awkward (albeit hilarious) TV interviews of all time. In the 1979 special, Andy feigns total ignorance of Cindy's career.
