And sources claimed the Adore You singer played it "pretty cool" when he was robbed.
They said: "He actually played it pretty cool, quickly giving the assailant cash, keeping himself and the guy calm and getting the situation over with. Understandably though it left him very shaken up afterwards."
Following the robbery, Harry is believed to have hired Sir Mick Jagger's security guard to keep him safe, especially during the BRIT Awards, which took place just days after the incident.
Another insider said: "Harry was on great form at the Brits, chatting to everyone and having a great time. But we did notice his bodyguard was with him that evening. That's understandable given that he was mugged so recently and has been the victim of a stalker in the past. Like Mick, he has to take security very seriously. And as Mick is such an idol of his, it makes sense that he would look to him to inspire his choice of staff - as well as his choices of fashion and hairstyles."
