An Irish model has been found dead just hours after she posted a cryptic message on Facebook.

Axar.az reports citing Dailymail.

Mother-of-four Alli MacDonnell's death has devastated friends and family who have paid tribute to the stunning 36-year-old.

Hours before she died she wrote on Facebook: 'Why is it ok for a man to call a girl a fat ugly c***?????? A seriously new level of pushing someone to the edge.'

Alli, who studied at Trinity College Dublin had recently celebrated her younger sister's 21st birthday and called her four children her 'world' on social media.

The model who was signed with the Andrea Roche's AR Model Agency also campaigned for autism awareness.

Friends took to the internet this afternoon to express their shock while calling the mother of children aged between two-years-old and fifteen, 'beautiful inside and out'.

It is not clear whether the post was linked to her death.

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