The 15-year-old has been flaunting a romance with Queensland schoolboy Bailey "Bazz" Lancaster on her Instagram account, and RadarOnline.com has the photos.
According to a report from News.com.au in Australia, the couple are believed to have been dating since September and the site claims Lancaster made comments on her Instagram account that alluded to their relationship but was later deleted.
Lancaster, a skateboarder and hockey player, commented on Sept. 28 underneath a photo of Bindi saying, "Mine. Back off boys. Getting pretty jelly" and then two days later wrote, "Also back off boys she's #mine."
When a follower asked if the two were dating, Lancaster reportedly responded, "You betcha buddy. Dating it up date style."
Lancaster has since deleted his comments and his Instagram account.
Bindi has referred to him on the popular social media site as one of her "best friends" and has posted photos of them together at a Taylor Swift concert, a Halloween party and a Neon Trees gig.
