Rachel McAdams' Hair: 2013 Hairstyle Changes to Red, 'The Notebook' Actress Pictured With Red Hair, Trouble in Paradise for Ryan Gosling and Eva Mendes?

When you're a leading lady in Hollywood, no change goes unnoticed. This is the case with "The Notebook" actress Rachel McAdams who dyed her hair red recently. The Canadian actress was pictured out and about with her new red locks, causing the Internet to take notice. Is it for the warmer weather that's just around the corner? Maybe it's because of her recent split from actor Michael Sheen, but either way, McAdams is making headlines with her new look.

According to People, McAdams has had the new hair color since February, shortly after her split with Sheen, which makes me think it was a getting over a breakup style change. McAdams is no stranger to hairstyle changes. She has sported a number of different hairstyles over the years, including blonde and brunette. The actress isn't the only female celebrity to switch over to red hair. "Glee's" Dianna Argon and "Modern Family's" Ariel Winter have also gone red recently.

McAdams was just spotted this week at Disneyland with her parents. The 34-year-old actress was dressed casually with a baseball cap on and leather jacket. With McAdams back on the market, who will be the next lucky guy to be in a romance with McAdams?

In an interesting side story involving McAdams' ex Ryan Gosling, the New York Post reported that Gosling flipped out on a photographer recently and also showed up without his girlfriend Eva Mendes. Gosling got heated after a photographer called Mendes "baby" outside the Bowery Hotel at the premiere of "The Place Beyond the Pines." The New York Post also reported that the couple remained apart for an Svedka-sponsored party. Gosling brought his mother to the party, which he has reportedly done in the past, but strangely he didn't interact with Mendes. According to the Post's source, "They stayed at opposite ends of the room from one another."

If this report is true, that is awfully strange. If you're dating someone and you're at an event together don't you hang out together? It's one thing to not be all over one another, but to not even interact? Do you think there could be trouble in paradise for Gosling and Mendes?
