Music mogul Simon Cowell has apologised after taking a potshot at singer Zayn Malik, who has left boy band One Direction. Cowell has now called it ‘a joke,’ reports mirror.co.uk. He was earlier slammed for saying: “Guys, who misses Zayn? We all get old but I’ve still got charisma.” The 56-year-old has issued an apology for his comment, admitting that it ‘backfired hugely.’
