We all know Bindi Irwin as the young, bright teen who won everyone's hearts — and the Mirrorball trophy — on Dancing With The Stars' 21st season.
But now, with her 18th birthday just around the corner, Steve Irwin's daughter is showing a more grown up side of her that we've never seen before!
On Wednesday, the Australia native took to Instagram to share a selfie… and she looks NOTHING like herself!
The 17-year-old posted a pic showing off a darker hair color and an ever-so-slightly revealing tank top with the word "Thelma" on it.
In consideration of Thelma and Louise and my friend who I've loved my whole life, Thelma. This shirt is for you 😘A photo posted by Bindi Irwin (@bindisueirwin) on Jun 15, 2016 at 7:40pm PDT
