Famed comic book creator and Marvel icon Stan Lee was hospitalized Wednesday night after suffering from shortness of breath and an irregular heartbeat.
“Stan is doing well and feeling good,” the rep said in a statement. “He is staying there for a few days for some check-ups as a safety precaution.”
PEOPLE has reached out to Lee’s reps for comment but has yet to receive a response.
Lee was recently photographed at the Black Panther premiere on Monday in Los Angeles, posing with the film’s star Chadwick Boseman, and then, later, with eager fans.
The film producer created the character in 1966 along with Jack Kirby, a comic book artist. Lee frequently makes cameo appearances in the Marvel films.
Lee’s wife, Joan, died in July 2017 at the age of 93. The former hat model married Lee in 1947.
Last year, Lee told THR how he knew Joan was the one for him. “She was the girl I had been drawing all my life.”
