A TWILIGHT fan has become a viral sensation after nutting off over Kristen Stewart's admission that she cheated on her partner and co-star, Robert Pattinson.
Emma Clark posted a YouTube video entitled How Could You Do This Kristen?! that brought back memories of Chris Crocker's infamous Leave Britney Alone viral video from four years ago.
Her reaction to confirmation that Stewart had cheated on Pattinson with her Snow White and the Huntsman director Rupert Sanders has had nearly half a million views in just one day.
Stewart issued a press release yesterday apologising for the scandal, and said: "This momentary indiscretion has jeopardised 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."
As 3 News reported, a few hours later, Clark - using the name "nuttymadam3575" - posted a video on YouTube showing her tearful reaction to the news.
"I thought it wasn't real. I thought they were just making it up, because I don't want it to be real," Clark weeped to the camera.
"I feel like everybody needs to back off, okay, this is none of your business. This is none of anybody's business. But her releasing that statement, it's like saying, 'Hello world, come on in'. It's like saying it doesn't matter. It's okay.
"I don't understand how she could do this. Why? Why would you cheat on Robert Pattinson?. What do you stand to achieve by cheating on Robert Pattinson?
" ... I'm so not okay with this."
Clark's Twitter feed includes a photo of her posing alongside Pattinson, and the post: "CongratuF**KINGlations Rupert Sanders. You just pissed off a million people cause you just couldn't keep it in your pants."
She also called Stewart a "hussy" in a subsequent tweet.
Latest reports suggest Pattinson has moved out of the Los Angeles home he shared with Stewart.
The scandal began when Us Weekly published intimate photos of Stewart and Sanders together.
Crocker posted his video four years ago to defend Britney Spears after she attracted negative press attention over a series of incidents, including shaving her head and attacking a car with an umbrella.
