Kate Spade's shocking suicide took the fashion world by a storm this gloomy Tuesday morning. While her immediately family has remained silent ever since the unexpected tragedy, her beloved brother-in-law, David Spade, has finally spoken out.

"Fuzzy picture but i love it. Kate and I during Christmas family photos," David captioned a sweet Instagram photo of him and Kate, 55, laughing in matching black attires. "We had so much fun that day. She was so sharp and quick on her feet. She could make me laugh so hard. I still cant believe it. Its a rough world out there people, try to hang on."

The Grown Ups actor—whose brother is Kate's widowed husband Andy Spade—also took to Twitter to share a charming snap of the late designer.

"Katy at my book signing. I love this pic of her. So pretty. I dont think everyone knew how f***ing funny she was... Its a rough world out there people. Try to hang on," David, 53, captioned the image of Kate laughing at him as he signed books.
