"These are the kind of things I hate when I read them" the actress, 34, tells BlackBook about being described as "pure" and "innocent" by the press. "It's interesting to be perceived as innocent. Innocent of what? I'm certainly not naïve."
Adams, who received her second Oscar nomination – the first for 2005's Junebug – for her supporting role in Doubt, and charmed audiences as Enchanted's Princess Giselle, may look the part of her characters, but that's where the similarities end.
"The sweet girl in Junebug is not who Amy really is," her costar, Embeth Davidtz, tells the magazine. "Amy's much naughtier than anyone I know. I can't give you examples because they are so beyond X-rated. She's got the wickedest sense of humor and says what nobody else would think to say."
Without divulging too much information, Adams (who's engaged to boyfriend Darren Le Gallo) herself admits, "I misbehave. I just do it in private."
But like any other hot Hollywood star, the Castle Rock, Colo., native enjoys nights out on the town, but always follows a self-imposed rule and "my secret tip": Taking cabs.
Adams's Butt Show"I have a lot of energy naturally and can be quite vivacious," she says, adding that dying her natural blonde hair to a vibrant red gave her a boost and "palpable shift" that "is hard to explain."
Up next for Adams is a role that might help shatter the "innocent" label she's been linked to with the help of some wardrobe changes. She'll swap the Catholic nun robe she wore in Doubt for a pair of snug jodhpurs as Amelia Earhart in Night at the Museum 2: Battle of the Smithsonian.
"It's going to be an Amy Adams butt show," she says. "I was like, 'That's a lot of information.' I'm not known for showing my a-- on camera, but there it is."
