Mr Greenwald, 56, took to Twitter to write a heartbreaking tribute Tuesday morning announcing Miranda's death, alongside photos with their two sons, aged 13 and 15.

Shortly after 8am on Tuesday 9 May, Mr Greenwald wrote: "It is with the most profound sadness that I announce the passing away of my husband, @DavidMirandaRio. He would have turned 38 tomorrow. His death, early this morning, came after a 9-month battle in ICU. He died in full peace, surrounded by our children and family and friends."
