Kate's older sister, Reta Brosnahan Saffo, told CBS News on Wednesday that she believes the 55-year-old designer - who was found dead of apparent suicide on Tuesday - was suffering from bipolar disorder.
"We've learned Andy Spade was not living at the family home ... he and Kate had separated and he was living in a nearby apartment". "So, Andy [her husband and David Spade's brother] and I were out, honestly, at a Mexican restaurant and he just said, what about handbags?" she said. "It was a complete shock".
First daughter Ivanka Trump, a fellow New Yorker with a clothing and accessories line, wrote on Twitter that Spade's death was "a painful reminder that we never truly know another's pain or the burden they carry".
"I, personally - I don't know about Andy - took off a good nine years raising my daughter, and absolutely adored every moment of it", she said.
'We'd been together so long, I was like, "Really? They loved each other very much". "Ask Daddy!" the note said, according TMZ.
He elaborated, "Kate was upset by the way the fashion community treated her".
The outside of a Kate Spade store is seen in Manhattan, New York, U.S., June 5, 2018. Spade, one of the biggest names in American fashion, was found dead Tuesday in NY after committing suicide, police said.
Tragically, the world lost another creative mind to the ravages of clinical depression this week when Kate Spade lost her life to suicide.
Spade also referenced media reports of a suicide note that had been reportedly left by his late wife.
In addition, a spokesperson for the Office of the Chief Medical Examiner confirmed the death of Spade, also known as Katherine Brosnahan, and accepted her case.
A source close to the Spade family tells ET that "Kate was a kind, generous, funny, warm and extremely private person. We honor all the beauty she brought into this world". "My daughter and I are devastated by her loss, and can't even begin to fathom life without her", he writes. That seemed to make her more comfortable, and we'd get sooo close to packing her bags, but, in the end, the "image" of her brand (happy-go-lucky Kate Spade) was more important for her to keep up.
This morning, "Extra" spoke to her former publicist, Rob Shuter, who said Kate "cared deeply about dignity, decency, kindness" but that "deep down, behind the ideal facade, there was a real sadness about Kate".
