"I hate water!" the actress and reality star, 37, tells Access Hollywood Live. "I'm never thirsty actually. I don't drink water."
As a result, "I don't sweat," says Spelling. "Isn't that weird?"
Even after not working up a sweat during a hard workout, the Tori and Dean: Home Sweet Hollywood star says she'll only take a sip of her homemade sparkling water – "If I have to."
And as adamant as she is about her distaste for water, Spelling is also firm about something else – expanding her family.
Already mom to Liam, 3, and Stella, 2, Spelling, who recently debuted her children's picture book, Presenting … Talllulah!, says she and husband Dean McDermott think they'll "go for another one."
Though she likes the idea of having three kids, "There ain't nothing in there yet!"
