Kristen Stewart, formally best known as Bella Swan from the "Twilight" series but most recognized now for cheating on teen heartthrob Robert Pattinson, has allegedly been "banned" from attending her former lover's premiere, Radar Online said.

The movie is set to have a limited release on Aug. 17, the Daily Mail reported. The red carpet event is supposed to take place a few days before on Aug. 13, without the likes of "K-Stew" apparently.

Radar Online reported that 22-year-old Stewart might plan on crashing the event so that she can talk to her old beau. It's been rumored that the two are no longer living together after two U-Hauls were spotted outside of their mansion last weekend and other reports added that the two have only exchanged "heated" texts since the fallout of their relationship.

In addition to Stewart potentially stalking Pattinson at the event, "movie bosses" do not want a media frenzy that will distract the public from the movie, according to Radar Online.

"Despite the fact Robert and Kristen have been communicating by cell phone, she will not be at the Cosmopolis New York premiere," a source said.

"Security was briefed and they were told that Kristen is not allowed anywhere near the red carpet or the after party."

"The decision was made because Robert just doesn't want to see her. There were fears that she could use it as a chance to talk to him in person and that sort of drama is not wanted at the premiere."

"There's also the fact that if she did attend, it would distract from the film premiere itself and the movie bosses are not interested in that sort of publicity."

"It's going to be Robert's first public appearance since the scandal broke - and they really want to make it less of a media circus than it already will be," an insider revealed to Radar Online.

Another rumor being spread about "R-Patz" was that he was too disheveled from the breakup to attend his public events, but the British actor's reps denied the claims.

"Cosmopolis is a film that Robert is very proud of and looks forward to supporting," the rep told People. "No confirmed engagements have been canceled. Any reports to the contrary are inaccurate."

Radar Online is reporting that Pattison, 26, has taken refuge at Reese Witherspoon's, his "Water For Elephants" co-star, Ojai, California ranch.

A source told Radar Online that Witherspoon offered Pattinson support because she knew what he was going through.

"Reese went through a very public cheating scandal herself when Ryan Phillippe went outside their marriage and hooked up with Abbie Cornish, so her first thought when she heard about Kristen and Rob was to reach out to him and make sure he was okay," the insider revealed to Radar Online.

"Reese knows what it's like to be on display when your heart is broken, so she felt like opening up her home to Rob was the right thing to do."
