Last night, Lady Gaga was supposed to take the stage in Brazil as part of the massive "Rock In Rio" festival that goes down every year. But just hours before her performance, Gaga posted a picture on Instagram of her with an IV in her arm, giving devil horns, apologizing to Rio for having to back out.
She also posted the official statement that was given for her having to bow out.
She followed THAT up by pointing out that she has such love for Rio, that a few years go she had "RIO" tattooed on her neck.
Gaga suffers from fibromyalgia, which is the source of her physical pain.
