Forty years later, Suzanne Somers and her husband still have that spark.
"Who wouldn’t want a relationship where you laugh, and you are in business together and you have a sexy life," Somers told Inside Edition
She compares her partnership with husband, Alan Hamel, to her success as an actress, adding that the couple hasn't spent a night apart in 37 years.
She says their relationship faced its biggest test when she unsuccessfully argued for equal pay on her breakout show, Three’s Company. She was ultimately fired.
Somers told Inside Edition “it hurt” to find out she was let go.
"I was absolutely stunned and heartbroken and I have never ever planned on that being the outcome of this," she added.
She bounced back in other television shows like Step by Step, a recent stint on Dancing With the Stars, a show in Vegas and, of course, the ThighMaster, of which 10 million have been sold.
Even when faced with health problems and the destruction of their Malibu home in a fire 10 years ago, Somers and Hamel have maintained their strong marital bond.
