Kate Spade married David Spade’s brother, Andy, in 1994, one year after they started fashion brand Kate Spade New York together.

“She was so sharp and quick on her feet,” Spade added in his tribute. “She could make me laugh so hard. I still can’t believe it.”

Kate and Andy Spade sold 56% of the brand to Neiman Marcus for $33.6 million in 1999. Liz Claiborne acquired the company in 2007, the same year Spade left her namesake brand.

“It’s a rough world out there people, try to hang on,” David Spade added.
