'I'm crying': Bindi shares heartbreaking moment from wedding

Fans of Bindi Irwin have been left sobbing after the wildlife activist shared a glimpse of her wedding day ahead of the full ceremony airing tomorrow.

Taking to Instagram Bindi announced her highly-anticipated wedding to Chandler Powell will hit screens in the US tomorrow but left some Aussie fans disappointed that the special will air as late as July Down Under.

In the meantime, she gave fans a glimpse at the big day, sharing a trailer and some gorgeous wedding photos with one heartbreaking moment sending everyone over the edge.

“We’re sharing every beautiful, challenging and special moment with you during this episode,” she wrote alongside the brief clip.

“I already have happy tears.”

It truly was tears all round, as the trailer revealed the moment brother Robert Irwin walks his big sister down the aisle.

The 16-year-old appears to hold back tears as he takes dad Steve’s place.

“To have that role to walk her down the aisle, it means so much,” he tells the audience, seeming to choke up with emotion.

In another heartwarming moment, Terry Irwin tells the audience that late dad Steve Irwin would ‘be proud’.

“I know that Steve would be proud and pretty sure he’d be crying,” she says.

In case that didn’t jerk any tears from you, photos published by Australia Zoo show a special commemoration to Steve where the newlyweds lit a candle during the ceremony.

Steve tragically died after being impaled by a stingray in September 2006.

Fans in floods of tears over adorable day

It seemed to be tears all round, as fans took to the post to share their reactions.

“Omg I’m crying,” one woman wrote.

“This makes me cry every time,” another fan agreed.

“My heart,” another wrote.

Bindi stirred up some controversy when she tied the knot with Chandler in a secret ceremony just hours before restrictions came into effect in Australia at midnight March 25, which now allow five people to be present at a wedding.

Some fans were happy for the couple, sharing their congratulations. But others called them out for setting a bad example.

“What would be even better would be if they set the example and only had a limited wedding. This isnt about denying people fun this is about keeping people safe. I'm completely disappointed in them,” one person wrote on Twitter.

“Suppose different rules for celebrities,” another said.

“She would've had workers from Australia Zoo and family there. Who cares what she does, move along,” one fan countered.

Bindi announced her engagement to Chandler in July last year, after he dropped to one knee on her 21st birthday.
