09 February 2021 Share with: The 51-year-old singer - who finished filming for 'The Masked Singer' UK in October and was revealed as Harlequin over the weekend - was left in pain for "about a month" after contracting COVID-19. She told The Sun newspaper: "I’m slightly asthmatic, so initially it was just a case of feeling like I was breathing through a pinhead, but it was only at times I had to use my inhaler. “The worst symptoms for me were the headaches. It was excruciating and constant. I was taking painkillers but after a while I had to stop because it wasn’t doing anything. It wasn’t even touching the sides.
