One look at Bindi Irwin's Instagram will show anyone that the star has a strong relationship with her mother Terri, but her newest post is extra special.
Alongside a family image which includes both her her brother Bob and late father Steve Irwin, the 18-year-old wrote: "Our little family forever."
"Thinking back to the many years of adventure and love. Happy Birthday, Mum," a nostalgic Bindi shared.
But Bindi didn't stop there, she also took to Twitter to post some intimate throwback family snaps that even included one of Terri and Steve on their wedding day!
Terri promptly responded, "You have truly made this my best birthday ever@BindiIrwin."
The mother-of-two and wife of the late Australian conservationist turned 53.
Happy Birthday Terri!
