A mum-of-four has been found dead hours after a mysterious social media post about being branded "fat" and "ugly".

Alli MacDonnell, 36, was one of Ireland's top models and was signed with the Andrea Roche's AR Model Agency.

News of her shock death came hours after she wrote online: "Why is it ok for a man to call a girl a fat ugly c***?????? Seriously new level of pushing someone to the edge."

It was not clear who she was referring to or when the alleged incident occurred, The Sun reported.

She was a single mum to four children, Alex, 15, Sara, 14, Harry, 9, and Siena, 2, who she described as her "world" on her Instagram.

Alli, who studied at Trinity College Dublin, campaigned for autism awareness as an ambassador for Autism Action after her son Harry was diagnosed with the condition in 2016.

As news of the mum-of-four's death emerged, heartbroken friends paid emotional tributes on social media.

Alli had only celebrated her younger sister's 21st birthday last week.


Model and actress Vivienne Connolly said she was "devastated".

Tori Dempsey-Walsh said: "You were not only beautiful on the outside but inside too. Such a loss to everyone who ever had the pleasure to know you."

Gillian Stapleton Mua said: "I'm so deeply shocked at this news. Rest in peace stunning Alli ... you will always be remembered for your beauty inside and out."

Stephanie Whelan added: "Absolutely devastating. What a beauty inside and out. No matter how beautiful we knew you were it's how you feel inside that matters.

"You were a very proud mammy and your children will grow up knowing how strong their mammy was and make you so proud. RIP beautiful. Shine bright like the diamond you were."

Another said: "This is just a nightmare, I'm so devastated for her and all her family and friends."
