Rachel McAdams  is one of the most naturally beautiful actresses we've ever seen, so we couldn't be more captivated by her latest Allure cover , shot by Carter Smith. The August issue, which hits stands on July 29, features the star wearing minimal makeup and a romantic Valentino  gown in a very relaxed environment — a meadow with a nearby creek in Harriman, NY. Fittingly, Rachel seems to be enjoying a moment of peace in her life. The actress stars in A Most Wanted Man, one of Philip Seymour Hoffman 's final films . "I learned so much from him. He really takes you under — he really took me under his wing," she says of Hoffman.
Meanwhile, Rachel's looking back on her past and anticipating the future at once. Reminiscing about her early roles in The Hot Chick and Mean Girls, Rachel has an idea of how she'd like her career to be remembered: "I'm hoping it's going to be complicated and have lots of dead ends and corners and sharp turns. I hope it can't be summed up too easily when I'm done." When asked whether she still believes in true love, Rachel remains optimistic: "Oh yeah, for sure. Absolutely." And, from the romantic vibes she's giving off in her shoot, we totally believe her.
But, she's not the only star opening up in the pages of the August issues. Blake Lively 's featured on her third cover of Vogue, and the star's dishing out details about her wedding  dress and her newly launched website, Preserve. Scroll down to see Rachel's and Blake's covers, along with the rest of the August lineup.
