The show must go on for funnyman David Spade.
The Tommy Boy star, 53, reportedly performed his stand-up comedy set on Friday night, June 8.
Kate, who was married to his brother Andy, apparently killed herself by hanging on Tuesday, June 5, authorities said.
According to E!, David told the crowd at Brea Improv Comedy Club in Brea, California, "Thank you for coming. It was a rough week, but I didn't want to cancel and I appreciate you all coming out here."
"And if my jokes don't work then I get sort of a free pass," David joked. "Thank you for coming out, I appreciate it."
On Tuesday after Kate's shocking demise, David posted photos of her in loving tribute.
Fuzzy picture but I love it. Kate and I during Christmas family photos. We had so much fun that day. She was so sharp and quick on her feet. She could make me laugh so hard," David wrote as a caption.
David's brother Andy had been married to Kate for 24 years and co-founded her accessories business. Andy and Kate also raised daughter Frances, 13, together.
"I still can't believe it. It's a rough world out there people, try to hang on," the Joe Dirt actor also wrote about his beloved sister-in-law.
Kate, 55, was found dead in her Manhattan apartment on Tuesday.
Authorities said she was found with a red scarf around her neck attached to a doorknob.
Spade's death stunned Hollywood stars who made her pricey accessories famous.
Her sister Reta Saffo shocked the designer's many fans by saying her death was "not unexpected."
Saffo cited her sister's self-medicating with alcohol and also revealed Kate had struggled with mental illness for years.
As RadarOnline.com reported, friends of David were concerned about him because he was so devastated by Kate's bizarre death.
Now he's apparently soothing himself by doing what he loves best, making people laugh!
