"She really is the most adventurous woman I know. Her life has been filled with extraordinary moments, just like the one captured in this photo," Bindi wrote alongside a photo of Terri posing with an elephant. "Mum does so much and always has endless amounts of time for us. We are truly blessed to have such a kind and patient mum. We love her with all of our hearts and can't wait to celebrate this special day."
Bindi also shared a sweet shot of Terri with her late husband, Steve Irwin.
"Soulmates forever. Celebrating my gorgeous mum's birthday today," she captioned the photo. "I was blessed with the greatest parents in the world������."
