K-Stew is “Terrified” About R-Patz’s First Post-Split Interview Tonight…

Kristen Stewart is reportedly “terrified” of what her ex-boyfriend Robert Pattinson is likely to say about her as he prepares to give his first interview since their split.

RadarOnline reports that Rob is set to make his first post-split public appearance tonight on The Daily Show with Jon Stewart in the States and Kristen is stressing over what the actor might say about her cheating ways.

Recently it was revealed that Kristen was doing the dirty on her boyfriend of three years with Rupert Sanders, the married director of her latest film Snow White and The Huntsman.

And while it is highly unlikely that Rob will go into details about what happened between the love birds, Kristen is still fretting over the possibility that he might mention the massive cheating scandal surrounding their split.

“Kristen is very, very nervous about Robert's interview with Jon Stewart on Monday,” said a source, speaking to RadarOnline.

“She’s confident that Robert, who has always been such a private person about his personal life, will keep quiet over the cheating scandal. But she does have some concerns that Stewart might poke fun at the situation in an attempt to get Robert to open up,” the source added.

While Kristen is known for having a sense of humour (yes, really she is!), apparently she doesn’t feel that her betrayal to Rob is anything to laugh at.

“She’s crossing her fingers that Jon doesn’t go there and instead concentrates on promoting Robert’s new movie, ‘Cosmopolis,’” said the source.

Do you think Rob will lift the lid on what happened between himself and Kristen?
