Devastating picture seen in the background of Bindi Irwin's latest post

Bindi Irwin and Chandler Powell have uploaded a lovely image to Instagram ahead of Christmas.

The happy couple were all smiles as they posed with their two dogs Stella and Piggy.

While it looked like love was most certainly in the air for the pair, some people noticed a picture frame in the background that has a sad history.

On the wall behind Irwin and Powell sits a series of pictures of their extended family.

One of the framed images contains the last snap of the Irwins before Steve's tragic death.

Bindi posted the original photo back in 2015 and captioned it with: "The last photo as a family, before I had to wave goodbye to my hero, for the last time. Dad, I love you."

Bindi and her brother Robert are young kids in the picture and Steve and Terri are dressed in their iconic khakis and are beaming with smiles.

Steve died in 2006 when he was just 44 years old after being pierced by a stingray barb.

His death on November 15 all those years ago has now been turned into Steve Irwin Day to commemorate the Aussie legend.

Bindi marked the day earlier this year by sharing footage of her famous dad explaining how important wildlife conservation is to him.

"Conservation is my whole life, my whole persona. What I want to be remembered for," Steve said in the old video.

And boy, is he remembered for it.

His daughter captioned the footage on Instagram to remind her followers to recognise Steve Irwin Day in their own way.

"Wear your best khaki and celebrate the greatest wildlife warrior the world's ever known," she wrote.

The day before Steve Irwin Day also just so happens to be Chandler Powell's birthday.

"Our family. My world. November 14 is one of my favourite days of the year, celebrating my incredible husband's birthday," Bindi said on Instagram alongside a collection of adorable, never-before-seen family snaps.

"Chandler, you are the strongest, kindest and most selfless man I have ever known.

"I wish I could find a way to express how much you mean to me."

She added: "I love you in every way, for all of my days. For me and Grace, our sun doesn't just rise and set with you, you ARE our sunshine. Happy birthday to the very best."
