Lady Gaga can't just dance  or even walk!

The 26-year-old pop star is apologizing to fans for postponing several concerts due to an injury that is preventing her from being able to walk, according to People.

"I've been hiding a show injury and chronic pain for some time now, [and] over the past month it has worsened," she explains on Facebook on February 12. "I've been praying it would heal. I hid it from my staff. I didn't want to disappoint my amazing fans."

"However, after last night's performance, I could not walk and still can't," Lady Gaga reveals. Sounds scary!

Lady Gaga apparently has synovitis, which causes severe inflammation of the joints. Her next four concerts have been postponed.

"I'm devastated & sad," she continues. "It will hopefully heal as soon as possible."

We're wishing Lady Gaga a speedy recovery!
