When Emma Stone and Nicki Minaj start to look a bit… similar—attention must be paid.

We’re not speaking of the platinum manes and big baby blues—it’s the electric pink hue slathered across the lips of the comedic actress and risqué rapper, as they were recently spotted rocking a look remarkably reminiscent of what we scoped on the Spring 2011 catwalks. (Who knew they even paid attention to the collections?!)

Variations of ‘pop art pink’ pouts popped up on both sides of the Atlantic; a matte fluorescent fuchsia at Diane Von Furstenberg in New York, and scintillant Schipparelli pink at Jil Sander and Fendi in Milan.

While the red carpet versions are a bit more muted and slightly shinier, the shock value remains the same.
