According to an US magazine report, the actress has instead dyed her hair a bright shade of red. She was spotted as a redhead while visiting Disneyland with friends and family.
McAdams broke up with British actor Michael Sheen this past February. The two reportedly met on the set of Woody Allen’s Midnight in Paris.
McAdams rose to fame with roles in the Tina Fey movie Mean Girls and the Nicholas Sparks movie adaptation of The Notebook. More recently, she starred in the romance movie The Vow, in which she (and her brunette-colored hair) re-learns to love her husband (played by Channing Tatum) after an accident causes her to suffer amnesia.
