David Spade on Sister-in-Law Kate Spade's Apparent Suicide: 'It’s a Rough World Out There'

The comedian's brother was married to the late designer.

David Spade has broken his silence about the apparent suicide of his sister-in-law, designer Kate Spade.

The actor and comedian's brother was married to Spade, who was reportedly found dead after hanging herself in her Upper East Side home on Tuesday.

"Katy at my book signing. I love this pic of her. So pretty," David Spade tweeted along with a shot of him and a smiling Kate Spade. "I dont think everyone knew how f***ing funny she was..."

Spade ended his tweet with an emotional plea to anyone who might find themselves suffering as his sister-in-law must have been.

"Its a rough world out there people," he wrote. "Try to hang on."

Spade's niece, "The Marvelous Miss Maisel" star Rachel Brosnahan, was also among those paying tribute to the fashion maven. 

"She had a light that words can’t capture but touched everyone she came into contact with," Brosnahan wrote on Instagram alongside a video of Spade dancing with husband Andy Spade. "She was exceedingly kind, beautifully sensitive, insanely talented, funny as heck and one of the most generous people I have ever known."

Meanwhile, reports have emerged that Kate Spade left a suicide note that addressed both Andy, her husband of 24 years, and their 13-year-old daughter, Frances.

Together, Andy and Kate founded the Kate Spade brand, which rose to prominence in the '90s with its vibrant line of handbags. The accessories later extended to clothing, eyewear and bedding.

They sold their shares of Kate Spade New York in 2006. A decade later, they started a new company, Frances Valentine, which focused on shoes and handbags.

Kate Spade New York has more than 140 retail shops and outlet stores in America and more than 175 shops overseas, according to The Associated Press.
