Bindi Irwin's boyfriend, Chandler Powell, wasn't going to let National Girlfriend Day go by without expressing how smitten he is with the Dancing With the Stars alum.
On Tuesday, the 20-year-old wakeboarder posted an adorable photo to Instagram of himself and Irwin in the water together. "Happy #NationalGirlfriendDay. Couldn't imagine going on these incredible adventures with anyone else," he captioned the image. "Thank you for making every moment so precious."

Powell's Instagram is filled with pics and sweet messages for his girlfriend, including a pretty photo of Irwin on her birthday last month. "You see her dancing on the TV, hand feeding crocodiles, running a zoo, and fighting for conservation all while spreading more love, light and happiness than anyone else," he wrote. "After all she works tirelessly for and dedicates herself to, all she asks for in return is a good book, a warm cup of tea and lots of hugs. If that isn't perfection I don't know what is."
The feelings are certainly mutual between Powell and Irwin. In July, the 19-year-old wildlife conservationist posted a pic of herself and Powell laughing on the beach, along with a quote by S. Khan that reads: "When it comes to love, do not ever settle for anything less than magical."
