Did Kristen Stewart Cheat on Robert Pattinson? [UPDATE: Yep.]

There might be trouble in paradise as far as the hush-hush yet heavily publicized relationship between Robert Pattinson and Kristen Stewart is concerned.

According to US Weekly, K-Stew was caught canoodling with her "Snow White and the Huntsman" director Rupert Sanders, and they claim to have photographic proof.

The photos aren't terribly convincing, but they have proved to be enough to make the story explode online, as speculation is running rampant. Though none of the involved parties have provided any comment, E! has statements from sources saying how "devastated" Stewart is over the whole thing, claiming it was a momentary "lapse in judgement" and not a continuing affair.

Perhaps more indicting than any photos are the reactions of Sanders' wife, model/actress Liberty Ross, on her Twitter account. Ross' first reponse after the news broke was a simple "Wow," but she also went back and removed a tweet that contained a picture of her with Stewart at the "Snow White and the Huntsman" premiere. Since then, Ross has taken the next step and deleted her Twitter account entirely.

Is that a confirmation of the affair? Not necessarily, but it's a good indicator that there's something going on. What do you think? Are the photos convincing? Did K-Stew cheat?

UPDATE:

Kristen has publicly confessed to the affair moments ago, saying, "I'm deeply sorry for the hurt and embarrassment I've caused to those close to me and everyone this has affected."

She added, "This momentary indiscretion has jeopardized the most important thing in my life, the person I love and respect the most, Rob. I love him, I love him, I'm so sorry."
