Kristen Stewart's "momentary indiscretion" could have a long lasting effect on her career. With the "Twilight" series' fifth and final installment "Breaking Dawn: Part 2" set to release in November, the leading stars Stewart and (ex?) boyfriend Robert Pattinson are expected go on a major promotion tour together.

Many believe the affair between Kristen Stewart and her married director, Rupert Sanders, could cause serious red carpet tension between "Twilight's" most famed couple. Entertainment expert Scott Huver believes that the already socially awkward stars will naturally be more reserved and cold due to the fresh scandal. "I would expect the press schedule to be altered significantly as a result of the recent developments. From the very beginning, neither Stewart nor Pattinson ever seemed especially comfortable doing press but have gradually appeared to find their comfort zones. Yet the scandal is almost certainly going to have them shying away from the direct glare of the media," Huver told FOX. "I would be bet that they'll do few to possibly no formalized interviews for the final film, except the most elite outlets and under tightly controlled circumstances. Other than that, expect carefully timed photo ops on the various red carpet premieres, and probably not together, unless some kind of peace can be brokered."

A public relations insider says the production team has no plans of any promotional changes. According to the source, "The film's release is still months away, and they are two young kids. Who knows what will happen, they could stay together or even move on and find someone else.  It won't be as hot a story by then."

It wouldn't be out of the ordinary for the pair to be separated on the "Breaking Dawn" promotion tour.  Even when they were a happy couple in the past, the two would sometimes be placed in separate interview rooms. Furthermore, during the international press circuit the actors would be assigned to separate appearances for different countries - they did so for "Breaking Dawn: Part 1".

"Twilight" actress Christian Serratos recently spoke out about her co-stars Stewart and Pattinson's relationship woes. Serratos doesn't believe Stewart's scandalous affair will affect ticket sales. She told Us Weekly, "Of course people are fans of us now, but I think above anything, they're fans of these characters. I don't think anyone's really gonna give a sh-t. They're gonna see the movie; it's going to be awesome." Serratos, who plays Stewart's mortal friend in the "Twilight" saga, hopes that the couple can work things out. "I support anyone who's in love," explained the 21-year-old actress.

The scandal definitely won't decrease the sales, in fact sales are sure to soar even higher for the already popular series. Many who never had an interest in the "Twilight" series may now be intrigued to see the on-screen chemistry between the now broken lovers.  Any publicity is publicity nonetheless.

Still, interviews during the press tour may be altered if not anything else. Certain questions will definitely be controlled and restricted.  "I feel fairly assured that any interviews granted will be on the condition that questions center solely on the film itself," Huver explained. "It will probably be best to keep them apart as much as possible, deftly choreograph the timing of their comings and goings, minimize the direct press interaction and maximize their individual face time in front of the fans. They are fortunate that the 'Twilight' franchise is such a colossal juggernaut that the film can largely sell itself, and there are plenty of other co-stars to pick up the slack and will be coached on how to deal with the 'Robsten' questions, of course."

When Stewart and Pattinson were first romantically linked, the press bombarded the two with so many dating questions that the film's rep had to firmly restrict personal questions being asked during interviews.

Ronn Torossian, CEO of 5WPR and author of the PR book "For Immediate Release," noted that Stewart's disgraceful affair is likely to have tarnished her image and may hurt her future career. However, Torossian concurs with Serratos' statement about ticket sales going strong in spite of the much talked about affair.

"They undoubtedly have contract provisions which will require them to promote the movie and do interviews," Torossian said. "I am sure they will do so without any public confrontations. And Stewart has already started addressing the rumors, so in three months, it won't be as intense a public issue."

Pattinson, who hasn't made any public appearance since news broke of his longtime girlfriend's infidelity, is set to resurface for his "Cosmopolis" press tour. The English actor has been reportedly hiding out at Reese Witherspoon's peaceful estate in Ojai, California, although his reps are denying those claims (possibly for privacy and protection). His new movie "Cosmopolis", in which he's the leading man, is set to hit theaters August 17.  A week before her secret affair was exposed, Stewart gushed over her beau's performance in the movie. It's doubted that she would accompany him on the red carpet of the premiere. However, the two are set to arrive together for the MTV Music Video Awards on September 6.

In other Kristen Stewart career news, her future in the sequel of "Snow White and the Huntsman" is also filled with uncertainty. According to several reports, Stewart's secret lover and "Snow White" director Rupert Sanders is getting pressure from his wife to not continue with the film. Sanders wife of ten years, Liberty Ross, co-starred along side Stewart in the film. The betrayed wife and model/actress, has allegedly forbid her husband of seeing Stewart again. "Liberty let it be known in no uncertain terms that Rupert can't direct the sequel to Snow White and the Huntsman," a source told RadarOnline. "They are trying to work things out after he was caught having an affair, and that is one of the sticking points. She just doesn't want him to ever work with Kristen again."

Before the scandalous pictures emerged causing heartbreak and humiliation to both Robert Pattinson and Liberty Ross, Sanders was praised for his "Snow White and the Huntsman" film and was set to create a sequel.  However, there's no signed contract confirming that venture. Ross uprooted herself and the couple's two small children, giving up her fashion career, to support her husband's Hollywood dream. Now, Sanders may have to do the sacrificing: His marriage or his dreams?
