Suzanne Somers puts her mansion up for sale for $27.5 million. Wait, what? She's that rich???

I'm ignorant on this one. Did she sell that many "thighmasters" and books? Or does her husband have the cash?.
Access Hollywood:
A year ago, Suzanne Somers lost her Malibu home to a fire that blazed through the town.
Luckily, she and her husband were able to seek refuge at her Palm Springs Home. But now that home is up for sale and Suzanne revealed to Access Hollywood’s Nancy O’Dell what exactly $27.5 million will get you.
“Why sell now?” Nancy asked Suzanne.
“I think it’s all about the fire. I think the house in Malibu burned down and we just decided to have a different life. A sexy, glamorous life, but more paired down,” Suzanne said.
