A cancer patient who inspired millions by dancing on camera in her hospital ward has died from the disease, US media say.
Ana-Alecia Ayala died on Wednesday afternoon at a Dallas hospital surrounded by friends and family.
More than nine million people have watched Ms Ayala's most popular video on Facebook and Instagram.
Friends paid tribute on Facebook and said they had been deeply touched by her joy for life.
"Your pure friendship and jolly personality brought everyone together! I am in total shock and deep prayer simultaneously," said dance instructor Oluremi Sano.
