Kristen Stewart: From Hollywood's highest paid actress to its second most famous home wrecker

At this month's Comic-Con convention in San Diego, Kristen Stewart, flanked by her longtime boyfriend and 'Twilight' co-star Robert Pattinson, joked with Fox News about what would happen if her fairy tale Hollywood ride came to an end.

“I've been so astonishingly lucky with who I've worked with,” Stewart told us. “It could all end for sure tomorrow, and that would blow my mind, but I'd be so happy with what I've done.”

What you have done indeed.

Just a few weeks ago, Stewart made headlines for beating out Angelina Jolie to become Forbes Magazine’s highest-paid actress.

Now she may also take Jolie's mantle as most famous home wrecker.

On Wednesday, Stewart, 22, admitted she had an affair with her married-with-two-kids “Snow White and the Huntsman” director Rupert Sanders, sending her personal and professional life into turmoil.

“I am deeply sorry for the hurt and embarrassment I’ve caused to those close to me and everyone this has affected,” Stewart, who has been dating her “Twilight” co-star Rob Pattinson for several years, said in a statement. “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.”

Sanders, who is married to model Liberty Ross, also chimed in with a public apology, declaring that he is “utterly distraught about the pain” that he has subsequently caused his family. Ross played the part of Queen Eleanor -- Kristen Stewart's mom -- in the recent “Snow White” film.

Ross wrote one word -- "Wow" -- on her Twitter account before dismantling the account altogether.

The overwrought public statement is out of character for the notoriously spotlight-shy Stewart.

“Sadly, the public statement from Stewart, who until recently had been fiercely private, indicates that she is desperate to salvage the situation by any means necessary, suggesting that she is doing it much more in service of winning back Pattinson than preserving her star status,” pop culture watcher Scott Huver told FOX411’s Pop Tarts column. “It may not have been the best way to handle it for her public image, but if Pattinson hasn’t been receptive to personal pleas, it may have been the only move left.”

PR expert Glenn Selig too was perplexed by the melodramatic nature of the statements.

“Both statements were so over-the-top and so dramatic it's almost like they believe they're starring in their very own movie,” he said. “It's very bizarre and strange, even by Hollywood standards.”

So will Stewart’s new-found standing as the pleading for forgiveness “other woman” hurt the forthcoming and final “Twilight” installment?

“Certainly the news that Stewart cheated on her beau and did so with a married family man nearly twice her age should be troublesome to even her most devoted fans,” Huver continued. “And at a time when she seems to have come into her own as a confident public figure, she may have to retreat from the spotlight, including press to promote the film, to avoid the inevitable questions about the scandal.”

The seemingly unwanted publicity does, however, add a twinge of off-screen suspense to the release of the film.

“Her core fan base is upset; she cheated with a married man and broke the rules. But angry fans have a short-term memory and I predict they will forgive her just like fans forgive most cheating celebrities,” explained entertainment writer Michael Cohen. “If anything, the scandal will enhance the intensity of the final film and fans of the couple will want to pontificate how much acting or not the couple share on-screen. This will for sure draw more numbers to the theater.”

The news is not surprisingly causing utter chaos on Twitter.

“I might actually watch twilight now that Kristen Stewart is a home wrecker. they don’t even go that far on jersey shore,” tweeted one, another wrote “for twilight fans, Kristen Stewart just met the one true death,” while scores of others offered their condolences to Pattinson.

“Girls may fantasize about being with Robert Pattinson. If he does become available it could reignite some excitement about him and the chance of being with him. Although it's a funny thing: Men are usually more appealing to women when they are with someone than when they aren't,” Selig noted.

Summit Entertainment, the film studio behind the “Twilight” phenonomen, did not respond to a request for comment.

And in a ripple effect, many are now speculating that the recently confirmed sequel to “Snow White and the Hunstman” may now be delayed in the wake of the adultery saga. Although Sanders was not contractually bound to do the sequel, it has been widely reported that Universal are trying to woo him back, and stars Stewart and Chris Hemsworth are under option to return.

Calls to the studio were not returned.

Stewart lamented to Elle magazine earlier this summer that her life was too “boring.”

"You can learn so much from bad things. I feel boring. I feel like, Why is everything so easy for me? I can't wait for something crazy to f**king happen to me. Just life,” she said. “I want someone to f**k me over!"

It looks like she may have done that all by herself.
