Billboard reports that Lady Gaga has announced that she will be postponing several shows on the "Born This Way Ball" tour due to synovitis, an injury to the joints that has left her unable to walk.

Gaga told her fans via Twitter that she is "heartsick" over having to miss the shows that were set for Feb 13-14 in Chicago, Feb. 16 in Detroit and Feb. 19 in Hamilton, Ontario, Canada.

"I've been hiding a show injury and chronic pain for sometime now, over the last month it has worsened," she tweeted. "I've been praying it would heal."

Gaga should be on the mend in time for her Miami show, which you could be seeing in the flesh courtesy of K945. We''ll keep you posted.
