Kristen Stewart, who will play the late Princess of Wales Diana in the forthcoming drama 'Spencer,' has spoken up about how much research she did to prepare for the role. "There are contradicting things from the horse's mouth," Stewart told Entertainment Weekly. You know, she doesn't always say the same thing in every interview. A lot of the facts were clearly, inconsistent.

"She is, unfortunately, and ironically, one of history's most unknown person, despite the fact that all she wanted was to get closer to others and expose herself." Kristen said not everyone will think she's perfected her performance, but she's confident she's tackled the role in the right way, reports media.

"There was something about fully absorbing her over the last six months leading up to today," she continued. I knew I'd come upon some sort of elemental force. It's fine with me if people have a lot to say about it not being a flawless impression." When Diana died in a vehicle accident when she was seven years old in 1997, the 'Twilight' actor had no concerns about taking the role.

"I knew even before I read the screenplay," she added. 'You're not going to say no to this, because who would you be in that situation?' I said. I would have felt like a complete coward. Especially since I'm such a stranger. I'm not from the UK, I don't have any particular investment in the royal family.

"So I was kind of this really clean slate, and then could absorb her in a way that actually felt very instinctive, you know?" The actress recently suggested the spirit of Diana gave her a "sign-off" for her performance.
