The erstwhile Lady Gaga stylist trades in his job as Mugler creative director for one at Diesel. So what’s in store for him?

Nicola Formichetti has left Mugler to become the new artistic director of Diesel. You’ll be able to see idiosyncratic stylist’s handprints all over the lifestyle brand’s look, beginning with its autumn/winter 2013 collection.

“I finally met somebody as crazy as I am,” the founder of Diesel, Renzo Rosso, said. “Nicola shares my vision and I find it incredibly inspiring to work with him.”

The Italian-Japanese stylist frequently collaborates with Lady Gaga and was fashion director of the now-defunct Vogue Hommes Japan. In 2010, he was hired as creative director for Thierry Mugler and was credited with bringing a younger demographic to the French label. He’s got similarly big plans for Diesel.

“We’re going to REBOOT!” Formichetti told us. “Hit refresh. That’s our first project: we’re ripping apart everything to re-build something bigger. I want to get the creative young people around the world to be part of the process.”

He kicked off his new role with the DIESELREBOOT project, which went live on Tumblr this week – he promises that it’s just one of the first steps in his grand design for Diesel. We bet Lady Gaga’s shedding a little tear – how’s Nicola going to have time to style Mother Monster now?
