Bindi Irwin breaks down crying at surprise picture of father Steve at the end of her dance

Bindi Irwin had her most emotional moment yet on Dancing With The Stars, crying as a photograph of her late father Steve came up on the screen at the end of her dance.

The Aussie star's freestyle dance, titled "Footprints in the Sand", left the judges, the audience and viewers at home sobbing ("violently sobbing" is probably a more appropriate description).

Bindi, 17, had no idea the photo would be there, with dance partner Derek Hough masterminding the surprise. We dare you not to ugly-cry – watch above.

After whispering "I love you" to Derek, 30, Bindi broke down again backstage and said on camera, "This whole experience has changed my life".

The judges awarded her 30 out of 30 again, following her perfect-score quickstep earlier in the night.

See her fly across the dance floor and her overwhelmed reaction during that dance:

Bindi has now made the top three for tomorrow's finale, competing against Backstreet Boys' Nick Carter and US army hero Alek Skarlatos.

After the show, Bindi wrote two emotional posts on Instagram, one featuring the last photo taken of her family before her father's death in 2006.
