Rachel McAdams Debuts New Red Hair, Looks Gorgeous (PHOTOS)

Rachel McAdams should stay single forever because she's never looked better.

The Canadian actress debuted a fiery new 'do at the premiere for her new film "About Time" in London on Thursday.

"The Notebook" star, who split up with "Midnight in Paris" actor Michael Sheen in February, was practically glowing in a flowing white-lavender Roksanda Illincic gown which featured a funky hologram belt and lime green stripe down the back. (If only Ryan Gosling could see her now...)

We love to gush over one of our favourite Canucks as much as we can; not only is the 34-year-old beautiful and a talented actress but the former one-half of McGosling is also down to earth (she prefers to live in Toronto rather than Los Angeles) and can play a fantastic mean girl.

One of the other great qualities about our girl crush is that McAdams can pull off basically any hair colour. Seriously, she looks great as a redhead, as a bright blond, with pink highlights and as a brunette.

Keep being you, Rachel!
