Terri Irwin is speaking candidly about her love for her late husband.
While chatting with The Courier Mail, per Yahoo! Lifestyle, Terri, 57, opened up about her past relationship with Steve Irwin, who died at the age of 44 in 2006 when he was struck by a stingray barb off the coast of northern Australia.
Responding to questions about her current love life, Terri told the outlet, "You know, and I keep saying this, and I think maybe 15 years later people are finally starting to believe me, Steve was it for me."
"That's just the way it is," she added. "I had a big, big love and it was enough to last a lifetime."
Terri and Steve first met back in 1991, when Terri stopped by a small reptile park in Australia where Steve had been working as a zookeeper at the time. The couple went on to marry in June 1992.
Continuing her conversation with The Courier Mail, Terri explained that she is alright with being on her own and is "too busy" to find new love anyway.
"I think when you become a young widow, it can be uncomfortable for other couples, that whole, 'Oh well, now she's single, is she looking around?' And my male friends are more comfortable, they can see I'm not chasing them," she said. "I'm too busy to chase anybody."

Terri also said she does hear talk about men she has been rumored to have been linked to over the years, but shut down any speculation that she has been romantically involved with any of them.
"I have kept track because it's kind of funny … let's see, apparently it's all the Hogans — that's Paul and Hulk; Russell Crowe, and most recently, it's Richard Wilkins," she explained. "I think the most flattering would be Russell because he is such a good person, and a very good friend to our family, and I actually do really love him because he loved Steve and they were such good friends."
