In August of last year, Terri revealed that she hasn’t been on “a single date” since Steve passed.

“I haven’t been on a single date since Steve died,” she told The Australian Woman’s Weekly.

“If I hadn’t met Steve, I probably would never have married because I wasn’t looking for love when I met him,” she said of her relationship with Steve. “What we had was incredible.”

Last month, Bindi opened up about her mother’s long-lasting love for her father to E! News

“My dad is still very much my mom’s soul mate. And I think that no matter what, Mom always says that they’ll always be married,” Bindi said in the interview. “And to her, mom and dad, they’re always going to be together. So in this life and the next, they’re a couple and a team. So I think that’s really important.”
