In her new book Uncharted terriTORI, Tori Spelling writes that she worries husband Dean McDermott could cheat on her.
But on Ryan Seacrest's KIIS-FM radio show Monday, she tried to downplay the remark.
"I'm a normal girl, and I worry about that stuff," she explained. "You know how girls are! Girls get jealous. You have to deal with that living all the time. It happens. We are who we are."
Spelling, 37, said her husband, 43 -- with whom she just renewed vows to celebrate their fourth wedding anniversary -- is confident in their relationship most of the time.
"He doesn't really get jealous," said Spelling, mother to Liam, 3, and Stella, 2. "I feel like an oddball being jealous all the time."
Despite a few on-air spats with McDermott on their Oxygen reality show, she said he is "great."
Not so great these days? Her relationship with her former 90210 costars.
With the exception of Jennie Garth, "All my 90210 cast members hate me!" the actress declared. "Jennie and I are still friends."
She said Tiffani Thiessen -- who gave birth to daughter Harper Renn in L.A. June 15 -- "doesn't talk to me anymore."
She thinks it's because her life went in a different direction.
"We were all great friends during 90210, we were friends after 90210, and they all came to my first wedding," Spelling said. "All of a sudden I marry Dean and I don't know what happened. I lost all my cast members."
