Kate Spade New York is mourning its founder. 

The brand, which was founded by Kate Spade and her husband, Andy, in 1993, took to Twitter on Tuesday to pay tribute to the designer, who died in New York City on Tuesday. Spade, who opened her first Kate Spade boutique in 1996, sold the brand in 2006.  She launched a new brand, Frances Valentine, in 2016.

"Kate Spade, the visionary founder of our brand, has passed. Our thoughts are with her family at this incredibly heartbreaking time," Kate Spade New York wrote in a statement posted to its social media accounts. "We honor all the beauty she brought into this world."  

The company continued to mourn Spade in a statement to ET on Wednesday.

"We at Kate Spade New York were incredibly saddened to learn the news that Kate Spade has passed," the statement reads. "Although Kate has not been affiliated with the brand for more than a decade, she and her husband and creative partner, Andy, were the founders of our beloved brand. Kate will be dearly missed. Our thoughts are with Andy and the entire Spade family at this time."

The NYPD confirmed to ET that Spade, 55, was found dead in her Manhattan apartment on Tuesday and her body was discovered by an individual that was employed by her. The cause of death is an apparent suicide at this time.

Spade is survived by daughter Frances and her husband, Andy, who is actor David Spade's brother.

Fans of Spade's work, from fashionistas to celebrities, quickly took to social media to honor the late designer. Read their tributes here.
