McAdams debuted a new shade at "The Wonder" premiere in Los Angeles in April 2013 with a hairstyle we usually reserve for doing laundry on Sundays, but she still (sort of) made the headband and messy top knot work.
Rachel showed off slightly more fiery locks at the London premiere of "About Time" in August 2013.
For now, Rachel is still a redhead. With a slightly more formal 'do, McAdams balances out her edgy dress at the August 2013 premiere of "About Time" in Munich. Of her red color, McAdams said, "This was the only color left! My mother is a redhead, so I thought maybe I could pull it off. If she could do it, maybe I could do it. I don't know, I just thought that it would be fun."
