Irwin snapped a picture of herself, along with her mom, Terri, her brother, Robert, Powell, and some family friends, while celebrating the holiday at the Australia Zoo, where the Irwins live.
Sometimes I think it would be nice to press 'pause' on time and live in these moments just a little longer. #ThanksgivingMemories," Irwin, 18, captioned the beaming group pic, which she posted to Instagram on Sunday.
That same day, Powell also shared a photo Irwin snapped while the two were driving through Queensland, Australia, along with a sweet message of love for his adoring girlfriend.
"Had the best time driving through the Glasshouse Mountains Christmas shopping. Hiking, looking for wildlife, stopping at little towns in the mountains," the 20-year-old professional wakeboarder wrote. "Wouldn't trade these days with you for anything in the world."
Over the Thanksgiving weekend, Powell came out to support Irwin and her family at the 10th annual Steve Irwin Gala dinner in Brisbane, Australia, which was established to honor Irwin's late father, Steve Irwin.
Before and during the event, the nature conservationist took over the Wildlife Warriors Instagram page, where she shared some pics from the black-tie event and some heartwarming memories of her father. Check out the video below to see more.
