Bad news for all Lady Gaga fans, as the 31-year-old pop sensation has postponed the European leg of her world tour due to ongoing health complications. As per E! Online, a statement from her label said, "Lady Gaga is suffering from severe physical pain that has impacted her ability to perform." The statement further read, "She remains under the care of expert medical professionals who recommended the postponement earlier today. Lady Gaga is devastated that she has to wait to perform for her European fans." Lady Gaga has been diagnosed with fibromyalgia, a chronic musculoskeletal disease that she talks about in her new documentary titled 'Gaga: Five Foot Two'. Later, after the European tour postponement was announced, the Grammy winner posted a picture on her Instagram, saying she has been "searching for years to get to the bottom of her condition". The news comes just days after Gaga was hospitalised and had to call off her planned performance at the Rock in Rio music festival in Brazil.
