Rachel McAdams has a beauty secret that often has her up before dawn. She revealed what she’s doing in the dark in a recent interview.

Actress Rachel McAdams, now 31, does something most can’t muster. She wakes up when it’s still dark and performs rigorous yoga.

“The earliest I’ll start is four-thirty. That’s my limit,” she told Vogue for a recent feature that also cited her habit of biking and walking wherever she goes, and a diet that arches towards healthy-gourmet. It also included the interesting detail that, as beautiful as McAdams always is, she wasn’t raised to focus on appearances.

“My mother never put an emphasis on looks. She let us grow up on our own time line,” McAdams told Vogue. “She never forced any beauty regimen into my world.”

With all this in mind, it seems unlikely McAdams has ever opted for plastic surgery – at least at this point. But in September 2009, she was one focus of a story about Hollywood procedures among actors, and her pictures drew speculation about a possible rhinoplasty.

“Rachel McAdams looks like she has had a rhinoplasty,” plastic surgeon Dr. Paul Nassif told MakeMeHeal.com. “The narrowing is the result of the collapse of the right middle vault, which causes the nose to look twisted. She also has an inverted V deformity of the middle part of her nose; in other words, the cartilage is collapsing. Her nose has also been over-reduced, so that it is collapsing and pinching as well.”

Dr. Sherrell J. Aston, on the other hand, disagreed.

“I do not believe that Rachel McAdams has had any plastic surgery,” he told MakeMeHeal.com. “She is very petite with pretty delicate features that look natural. If she did have surgery her doctor did a great job! I think that her look gives her a lot of diversity.”

If Rachel McAdams has had any plastic surgery on her face, it would come as quite a surprise. Smart money, however, hints that she hasn’t, despite what some surgeons say.
