Smiling, it was clear she was joking.
Pushing it further, Wilkinson laughed, "Have you told him?"
Irwin said, "I'm calling him right now!"
Irwin and Crowe are great friends.
She gushed "I do really, really think the world of him."
"He loves wildlife, he is very considerate about helping what we are doing and is a good guy."
Crowe has also spoken out about his friendship with the Crocodile Hunter's wife.
"I was great friends with Steve and his wife and his kids are really important to me. They're beautiful people," he told Newscorp.
"Terri is one of the greatest women I've ever met in my life, without there being implication of intimacy or whatever," he said.
"You know I do love Terri Irwin, I love her kids and I love how she's kept the memory of Steve alive, and respected the work that the two of them had begun and she's an absolute champion."
