Sienna Weir dead at 23 – Miss Universe finalist taken off life support after horror ‘horse riding accident’

But the details of her tragic passing have not been revealed.

Speaking after her death, heartbroken boyfriend Tom Bull, said: "We loved with a love that was more than love."

Tributes from friends and family also flooded social media, with many expressing their condolences on her final Instagram post.

A pal wrote: "Heaven has gained the most beautiful angel today. I'll miss everything about you Sienna, I love you."

She added that her smile "lit up every room" and that she had been "so lucky" to have known the aspiring model.

Her modelling agency, Scoop Management, shared several photos of the model, stating that she will “always be remembered”.

The rising star was among 27 finalists in the 2022 Australian Miss Universe competition.

She shared her experience during an interview with Gold Coast Magazine last year and revealed she had been riding since a young age.

She said: "My family aren't quite sure where this passion came from but I've been horse-riding since I was three years old and can't imagine my life without it.

";I travel to rural Sydney 2-3 times a week to train and compete around New South Wales or broader Australia every other weekend."

Photographer Chris Dwyer also posted a touching tribute to the star following her tragic passing.

He said: "You were one of the kindest souls in the world, you lit up the room and the world is a lot darker now that you are gone.

"Hope wherever you are, you're being the gremlin we all know and love.

"Miss you so much already."

The model had a double degree in English literature and psychology from Sydney University.

It was also revealed that Sienna had plans to move to London to be with her family and further her career.
