Lady Gaga's Chicago Surgery? Is Her Bad Hip Getting Fixed Here?

CHICAGO — After canceling shows in Chicago and Detroit last week due to a "severe inflammation of the joints," Lady Gaga went into surgery Wednesday morning.

In a tweet sent out about 7:30 a.m., Gaga said, "Going in for surgery now. Thank you so much for sending me love and support. I will be dreaming of you."

The singer was spotted on Michigan Avenue over the weekend in a wheelchair, which she named "Emma," according to her Twitter account.

Gaga has spent a lot of time in Chicago since she began dating "Chicago Fire" actor Taylor Kinney

On Wednesday night, Gaga posted the following message on her fan site:

Monsters, You really gave me a lot of strength today. Everything happened so fast, but when it came time to face it I reflected on the many stories and experiences you've shared with me about your lives. Meeting you backstage, reading your letters, watching you communicate with fans from around the globe to form a community that supports one another--You have completely blown my mind. As they wheeled me into surgery today, I thought about all of your pain and perseverance,  your unique family situations, school environments, health issues, homelessness, identity struggles -- sometimes you are so brave that it terrifies me. I wonder how it's even possible. So I thought to myself, I'm alive, I'm living my dream, and this is just a bump in the road. I'm grateful because this is temporary, and for some it is not. You have changed my life. I love you and am proud to be a part of your lives. If you can do it, I can do it too, and if we stick together we can get through anything. Love, Gaga

"The Born This Way Ball" was scheduled to swing through Chicago on Feb. 13, but her doctor recommended she stay off the stage because of synovitis, a "severe inflammation of the joints" that has impacted her hip.

"I am completely devastated and heartsick," Gaga said. "I've been hiding this injury and pain from my staff for a month, praying it would heal, but after last night’s performance I could not walk."

She also canceled shows in Detroit and Canada.
