The 22-year-old actress made the comments in an interview with Entertainment Weekly in mid-July, conducted alongside boyfriend Robert Pattinson, just around the time of her then-secret illicit fling with Rupert Sanders.
Stewart explained she just prefers being herself - and doesn't like the idea of being branded a phony in the interview, which was published today.

Pattinson last November at
the UK premiere of Twilight: Breaking Dawn Part 1, says she doesn't like
fake people in an interview conducted just before her cheating scandal
'I don't like people like that...' Stewart said. '...People who are a complete non-person but somehow through the lens seem like they are "on" and interesting and engaged.
'I care way more about the people standing in the room,' she went on. 'I don't want anyone leaving and saying, "God, that girl is so fake".'

pulled out of the London premiere of On The Road next week
Just weeks after the interview, pictures were published of Stewart and her Snow White And The Huntsman director Sanders, kissing and cuddling during a series of secluded stop-offs around Los Angles.
It prompted Stewart to release a public statement apologising to 26-year-old R-Patz for what she described as a 'momentary indiscretion'.

Angeles screening of Twilight in May
Apparently she is 'too ashamed' to show her face following her infidelity - and clearly pasting on a smile for the cameras is not something she is capable of doing, in light of her comments to EW.
An added edge of discomfort likely to have sealed the deal, is that co-star Tom Sturridge (the father of Sienna Miller's baby) is due to attend the August 16 soiree - who happens to be R-Patz's best bud.
A source told RadarOnline: 'Kristen won’t be doing the red carpet for On The Road, she’s too ashamed to show her face in public right now.
'After everything that has been said, and in light of the revelations that she cheated on Robert with director Rupert Sanders, she’s running scared at the moment.
On The Road, from Brazilian director Walter Salles, is the film version of Jack Kerouac’s novel.
The star-studded cast also boasts performances from Amy Adams, Kirsten Dunst, Viggo Mortensen and Steve Buscemi - along with protagonists Garrett Hedlund and BAFTA-nominee Sam Riley.
Meanwhile Stewart has also reportedly dropped out of her latest film, Cali.
In conjunction with K-Stew's departure, Gossip Cop are claiming that Amber Heard is joining the cast, although it has not been confirmed if she will take on the role Stewart was supposed to be starring in.

Part 2
The film follows lovers Mya (Stewart) and Chris (Alex Pettyfer) who run away after selling a fake snuff film, only to return to Los Angeles years later to rescue the woman’s younger sister from a bad mob.
Director Nick Cassavetes, who gave us The Notebook and gritty Alpha Dog, is scheduled to be the man behind the lens, while K-Stew was reported to act as producer too.
