Another added, “How?? Why??? Too many question, but too sad. Jet Li!!!”
Others expressed how shocked they were at the 55-year-old's appearance, even questioning if it was really him.
Five years ago, Li revealed that he was suffering from hyperthyroidism and a heart condition. At the time, his doctors said he could “either continue making [action] films" or stop and avoid spending the rest of his life in a wheelchair.
Despite his illness, Li has appeared in several movies, including “League of Gods” and “The Expendables 3.” He has also signed on to star as the Emperor in the upcoming adaptation of “Mulan,” which is in pre-production.
In a statement to USA Today, his rep said, "We appreciate everyone's concern. But Jet is completely fine. There's nothing wrong with him. There's no life-threatening illness. He's in great shape."
