Now he's thrown us for a loop by casting an unexpected face in Saint Laurent's new ads: Marilyn Manson.
A photo of the new campaign was shared by both Nicola Formichetti and SCENE's Peter Davis via social media, with Davis writing on Facebook: "Marilyn Manson in the new Saint Laurent ads. Thoughts?" On Instagram, Nicola wrote simple, "Amazing" with a slew of hashtags.
We can't say we saw this one coming, seeing as Manson isn't exactly a red carpet regular or fashion mag cover star. But he does fit the new profile Slimane's building for Saint Laurent: dark, edgy and slightly reminiscent of the '90s.
Then again, it remains to be seen if Manson's face will sell clothes. Check out a sneak peek of the Saint Laurent menswear campaign. Do you dig Manson as the face of one of fashion's most iconic brands?
