Even big-time Hollywood actresses aren't immune to the magical draw of the Happiest Place on Earth. Rachel McAdams stepped out for a fun-filled family day at Disneyland on Wednesday, April 3, with her parents and a few friends -- and a new look!

The stunning Vow actress hid her newly auburn hair in a ponytail under a baseball cap as she and her small group of pals wandered around the amusement park.

McAdams has previously spoken out about her love and admiration for her parents, Sandra and Lance McAdams, and her hopes to find a love like theirs.

"I had a great example of love in front of me, and that's probably what makes me such a romantic, because I've seen it firsthand," she told the June 2011 issue of Elle magazine. "You grow up and you assume that everyone is like [my parents], and you quickly realize that they're not, and then you have those days when you wonder if you're going to find it for yourself."

"It's such a hard thing to find," she continued. "I think it was more that realization that rocked me."

McAdams, 34, dressed down for the occasion, wearing a yellow T-shirt, jeans, a black leather jacket and boots. Maybe the newly single actress was trying to keep things low-key for a reason?

The Midnight in Paris actress, who split from her costar Michael Sheen in late February, was singled out at a Toronto Raptors game on Feb. 25 and given a big mascot hug, a plush toy, and a bouquet of red roses in the endearing moment.
