GREAT SCOTT: Jeremy Scott was one of the few who knew that Madonna would be Drake’s surprise guest at Sunday’s Coachella finale because he had worked out the singer’s Moschino look — her second one in a week after “The Tonight Show” — ahead of time with stylist Arianne Phillips. “I was watching from the front with Katy Perry and Rihanna and even they didn’t know, to give you an idea of how insider it was,” he said of Madge’s appearance. “It made me really happy that she gave me such a great homage, with her dancers wearing pieces from my Adidas collection as well,” said Scott, who stayed an extra day in the desert. “The pull of Coachella was too strong to stay away,” he said, though he’s “more selective” about which performances he goes to nowadays. “I went to see Bjork like 12 years ago, so I’ve definitely seen the festival in all its incarnations, and it only seems to get bigger and better.” Now that he’s conquered the Super Bowl and Coachella, the Met Ball is the next marquee event on Scott’s list, though he’s staying mum on who his date — or dates — will be.
