Bindi Irvin, wildlife warrior and daughter of popular crocodile hunter, Steve Irvin, posted a picture of herself on Instagram on Sunday, along with a caption that hinted that she was in love. This has added to the speculation that the 16-year-old youngster might be in a relationship.

After months of speculation that Irvin is dating her mother's assistant, Luke Reavley, who is eight years senior to her, Irvin has finally posted a quote that says, "When we are in love, we are both completely in danger and completely saved." The caption is taken from author Ava Dellaira's best-selling book, Love Letters to the Dead.

Irvin posted it along with a picture of herself looking and smiling away into a distance, giving the impression that she is indeed in love!

When rumours about Irvin dating Reavley began doing the rounds, a spokesperson for the Irvin family told Daily Mail Australia that the two were "just friends" and "Luke is the Irwin family's executive assistant." He assists Terri, Bindi and Bob, so he's often with them, said the spokesperson. Luke is known to be close to the Irvins ever since he joined them in 2007.

Though it's not clear whether Luke and Irvin are in a relationship, the two are certainly very good friends. Irvin had on Instagram posted a picture of herself with her 'good friend' on his birthday earlier this year, describing him as "the greatest friend." Luke too posted a selfie of himself and Irvin on her birthday, which was weeks later.

On her 16th birthday in July, Bindi told the interviewer Lisa Wilkinson that she was beginning to get male attention. "Boys start looking at you differently!' she said, and added that she was not yet ready for a boyfriend.

Meanwhile, on Sunday, Irvin also posted an old picture of herself with her father, on the occasion of Father's Day, along with the message, "Dad, I miss you every day. You are my superhero and my whole world. I wish you could be here, but I will do my best to make you proud. I love you more than words. Forever and always."

The special event organised on the occasion of Father's Day at Australia Zoo's Zoom event on Sunday was a product of a five-year partnership with RACQ, designed to help fund Wildlife Warriors conservation projects, including the Australia Zoo Wildlife Hospital.

The event was a huge success and the team hopes to repeat it next year, reported Sunshine Coast Daily. Irvin fascinated the audience and did not let the bad weather affect the huge crowd that had come to the Zoo. "It (rain) happened in the middle of the show but people still stuck around, Bindi fed the crocs in the rain as she's very good at it," an Australia Zoo spokeswoman said.
