The young star showed the size of her heart over the weekend when she visited fans at a Los Angeles children’s hospital, including Alex, a huge fan who could hardly contain her excitement for Irwin's visit.
For the Halloween meet-and-greet, Alex was dressed in a cat mask and a tiger-striped headband with black ears attached, giggling nervously as she waited for 17-year-old Irwin and her mother, Terri Irwin, to arrive.
"You are so beautiful, dear!" Irwin gushed upon entering the room and meeting Alex. "I love your Halloween costume."
The two hung out and told jokes, including a terrible knock-knock joke that made Irwin laugh much harder than her young friend. Then they posed for photos together, with Alex still looking over the moon with excitement about meeting the celeb.
According to People magazine, Alex wasn't the only patient Irwin visited at the hospital, and she reportedly told Entertainment Tonight the whole experience was "super emotional."
"A few people have said, 'I wish you brought an animal,' so next time I'll see if I can bring an animal," she said, revealing that she plans to make a habit of visiting fans.
Irwin isn't alone in loving that kind of experience. While Irwin is competing on the current season of Dancing with the Stars, a former DWTS pro, Maks Chmerkovskiy, surprised an 82-year-old fan of his with a private dance lesson at his New Jersey dance studio last Thursday.
