Ann Reinking, the iconic Broadway star best known for playing Roxie Hart in “Chicago” and for being the muse of Bob Fosse, passed away on Saturday in her sleep. She was 71 years-old.

Reinking’s sister-in-law Darhla King told Variety that Reinking died in her sleep in a hotel room while visiting her brother in Seattle, Washington.

“The world and our family have lost a vibrant, amazing talent and beautiful soul. Ann was the heart of our family and the life of the party,” Reinking’s family said in a statement. “She was visiting our brother in Washington state when she went to sleep and never woke up. We will miss her more than we can say. Heaven has the best choreographer available now. I’m sure they are dancing up a storm up there! Annie, we will love and miss you always!!!”

It was the dancer and choreographer Christopher Dean, a teacher of Reinking’s niece, who first announced her death on Monday.

“The lights on Broadway are forever more dim this morning and there is one less star in the sky,” he wrote on Facebook. “The good news is that heaven has the very best choreographer on earth now.”

Reinking kicked off her career in the Seattle Opera House production of “Bye Bye Birdie” in 1965 before making her way to Broadway, where she was cast in the ensemble for the 1969 production of “Cabaret.”

The star is perhaps best known for playing the role of Roxie Hart in 1977’s “Chicago” on Broadway, replacing Gwen Verdon. She would go on to reprise the role on Broadway in the 1996 revival of the famed production.

“The hope is that in rediscovering ‘Chicago,’ audiences will rediscover what theater was,” Reinking told The New York Times at the time of the show’s revival. “It was sophisticated, complicated, adult.”

Other roles on Broadway for Reinking included parts in “Sweet Charity,” “Over Here!” and “Goodtime Charley.” On the big screen, Reinking starred in movies like “Annie” and “All That Jazz,” Fosse’s autobiographical movie in which she played a fictionalized version of herself, as the main character’s girlfriend and one of his muses.

Reinking spent years being Fosse’s companion, and she was played by Margaret Qualley in FX’s 2019 limited series “Fosse/Verdon.”

“I really did watch her [on video] in the back of a minivan on my way to dance countless times,” Qualley told IndieWire of Reinking in 2019. “I was really nervous because I wanted to do right by her. I looked up to her for so long, was so familiar with her. More than anything, I wanted her to like it.”

Reinking is survived by her husband, Peter Talbert, and her son Chris.
