Sources close to Lebanese singer Assi Helani have denied rumours he underwent plastic surgery, after anonymous reports claimed he had gone under the knife during a recent visit to London. “Hellani is an athlete and he follows a diet,” the source told Arabstoday exclusively. “He recently caught a nasty cold and took some drugs on the order of his doctors.” One of those drugs, cortisone, had caused Helani to put on weight, the source claimed. Helani was reportedly singing for a businessman at an exclusive party in London.
