Spade was married to Andy Spade, the brother of comedian David Spade. The couple started her company together in 1993. The pair sold the brand in 2006 and launched a new accessories company, Frances Valentine, in 2016. The famed designer is survived by a 13-year-old daughter, Frances Beatrix Spade.
"Fuzzy picture but I love it. Kate and I during Christmas family photos. We had so much fun that day," David captioned the shot. "She was so sharp and quick on her feet. She could make me laugh so hard. I still cant believe it. It's a rough world out there people, try to hang on."
"Knowing Katy, this is how she would want to be remembered. She had a light that words can’t capture but touched everyone she came into contact with," Brosnahan captioned the video of Spade and her husband dancing to a mariachi band. "She was exceedingly kind, beautifully sensitive, insanely talented, funny as heck and one of the most generous people I have ever known. She was effervescent. Hug your loved ones extra tight today."
