Actor David Spade shared a warm Christmas memory in a tribute to sister-in-law Kate Spade, who was found dead Tuesday in her New York City apartment of an apparent suicide.

“Fuzzy picture but I love it,” Spade wrote late Tuesday in an Instagram post, sharing a picture of him and the late designer. “Kate and I during Christmas family photos. We had so much fun that day.”

Asking for help

The suicide rate in the United States has seen sharp increases in recent years. Studies have shown that the risk of suicide declines sharply when people call the national suicide hotline: 1-800-273-TALK.

  • There is also a crisis text line. For crisis support in Spanish, call 1-888-628-9454.
  • The lines are staffed by a mix of paid professionals and unpaid volunteers trained in crisis and suicide intervention. The confidential environment, the 24-hour accessibility, a caller’s ability to hang up at any time and the person-centered care have helped its success, advocates say.

    The International Association for Suicide Prevention and Befrienders Worldwide also provide contact information for crisis centers around the world.

    “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.

    The luxury fashion company Coach announced it was purchasing the company for $2.4 billion last year.

    Kate and Andy Spade had one daughter together.

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