Emma Stone, is that you?

Michelle Monaghan is the latest celeb to become a redhead, and between her fiery hair color and wavy style with blunt bangs, the former brunette now bears an uncanny resemblance to The Help star.

Monaghan, 35, debuted her new hue at the Toronto Film Festival on Monday. Wearing a white mini dress with burgundy suede Brian Atwood pumps, The Machine Gun Preacher actress posed alongside her co-star Gerard Butler, 41.

On Sunday night she was recognized at the Creative Coalition's 2011 Spotlight Initiative Awards for her work in the film, which is based on an inspirational true story of a drug dealer who transforms his life.

"To be honored with a Spotlight Award means a lot to me, actually," Monaghan said. "I think it's important to recognize projects that take a risk, and this one isn't afraid to confront the audience with some tough material."
