Lady Gaga has promised to keep performing until she nears her 60s. The 39-year-old singer made a pact with fans at London’s The O2 to be back on the same stage in 20 years “no matter what”. If I come back 20 years from now will you come to the show? On her Instagram Stories, she wrote: “Hi everyone I am really so so sorry but I need to postpone tonight’s show in Miami. I love my fans so much, respect you and hope you can accept my sincere regretful apology.”
