This incredible love story is still going.
"I haven't been on a single date since Steve died," she said. "If I hadn't met Steve, I probably would never have married because I wasn't looking for love when I met him. What we had was incredible."
Irwin met Steve in 1991 and the couple got married in June of the next year, after just eight months of dating. They had two children together, 18-year-old Bindi and 12-year-old Robert. They were married for 14 years when Steve died after being pierced in the chest by a stingray barb in September 2006.
Irwin told ET that she doesn't want to date again because she's already had her "happily ever after."
"I still feel immense love and loyalty to Steve. And I've got great kids, I've got a very full life, and while I'm lonely for Steve, I'm not a lonely person. I think for other people who have lost someone and have loved again, it's a beautiful thing but it's just not really on my horizon."
