Fans Can't Believe How Much Bindi Irwin's Daughter Grace Has Grown in New 'Twinning' Photo

Bindi Irwin 's fans can't keep up with how fast her little one has grown.

Users on social media were in disbelief over how much the Australian zookeeper's 3-year-old daughter, Grace Warrior Irwin Powell , has grown, after her grandmother, Terri Irwin , shared a sweet photo of the preschooler.

Taking to Instagram , Terri—or "Bunny" as Grace calls her—shared a photo of Bindi, 26, posing in the mirror behind Grace while both the mother and daughter sported matching yellow headbands.

"Grace is so proud to have a hair band just like her mama's. 💕," Terri, 60, wrote in the caption, while awestruck fans flocked to the comments to discuss how big Grace has gotten.

"I cannot believe how tall she is already," one fan wrote, while someone else said Bindi and her mini-me were "twinning."

"This little beauty is growing soo fast," another fan pointed out.

"Wow, those Irwin genes are prominent, she looks just like you," one person wrote to Bindi, the daughter of the late Crocodile Hunter star Steve Irwin .

Bindi also couldn't help but gush over the sweet photo with her little one, commenting on Terri's post to call Grace, "My buddy 💛💛💛."

The TV personality gave birth to Grace in March 2021, a year after tying the knot with her husband, Chandler Powell .

Since having her daughter, whom she calls a "miracle," Bindi has publicly spoken out about being diagnosed with endometriosis , and the toll it's taken on her body and her family.

While sharing the details of her health journey via Instagram in March 2023, Bindi encouraged her followers to "Please be gentle & pause before asking me (or any woman) when we'll be having more children."
