The faux pop star and his entourage arrived just as his show was about to begin, having apparently fooled security at the London Fashion Week event.
The "pop superstar" was seated in the front row next to eccentric fashion doyenne Isabella Blow complete with sequinned lobster clasped to her head.
Before the show began a white-coated lab technician walked through the Queens Gate tent outside the Natural History Museum where the show took place spraying scent in advance of the "star".
From that moment Macdonald could have sent models down the catwalk wearing a series of paper bags, not a single person would have noticed.
