Bindi Irwin marked the 15th anniversary of her dad Steve Irwin's death with a special tribute to her baby daughter Grace Warrior.
The 23-year-old honored her late father in a touching post on Instagram, featuring an adorable smiling shot of her 5-month-old daughter.
"This sweetheart has been watching her 'Grandpa Crocodile' on the projector at our camp here on the Steve Irwin Wildlife Reserve. She lights up when she sees him on screen," she wrote alongside the image.
"I wish with all my heart that dad could hug my beautiful girl."
She added: "It's been 15 years since he passed away. I hold on to the thought that he's her guardian angel now, watching over the most special part of my life, Grace Warrior."
Steve - who was also known as the Crocodile Hunter - passed away on September 4, 2006, after his heart was pierced by the barb of a stingray while filming at the Great Barrier Reef in Australia.
The world was left shocked and saddened by his death. He was 44.
Before she welcomed her bundle of joy with husband Chandler Powell on their 1-year wedding anniversary, Bindi told ET that her dad would have been a good grandfather.
"He would've been a good, good grandpa. Yeah, he really would've been," she said in February.
"I don't think we would've ever seen our daughter. He would've just whisked her away into the zoo and it would've been perfect."
"It is so nice that we'll be able to introduce her to her grandfather through all of the documentaries. It's really special," she added.
What's more, Bindi told The Bump that her daughter's nickname, Baby Wildlife Warrior, was a tribute to her late father.
"My dad was the first person to create the term 'Wildlife Warrior.' Being a Wildlife Warrior means to stand up and speak for those who cannot speak for themselves," she explained.
