Kristen Stewart Jealous of Scarlett Johansson?

"Twilight" will soon hit its' end by November of this year but it doesn't mark the end of the "Robsten" duo's film career.

Despite doing films separately, Robert Pattinson and Kristen Stewart have gone filming from one movie to the other. It looks as if one film Robert is set to work on with another blonde bombshell has got Kristen Stewarts' panties in a twist.

From "Harry Potter" to "Twilight", Robert Pattinson has had his share of lovely onscreen love affairs. In Pattinson's' latest flick "Bel Ami", the 26-year old manages to swoon the hearts of more than three women. Now, with "Cosmopolis" in talks, Robert is also set to star in "Hate Mail" opposite the voluptuous, Scarlett Johansson. This makes fans wonder, what would Kristen Stewart think of?

Kristen Stewart is known to keep all her relationships and family details private. Stewart calling Pattinson her "f*cking" boyfriend" was already a bold move based on the fact that she's closed off. Even PDA moments aren't all easy to capture on paparazzi cameras and if they manage to, "Robsten" fans immediately feed on them.

Basing from all the couples' PDA and red carpet moments, does Kristen Stewart strike as the jealous type?

With Robert Pattinsons' new pairing with Scarlett Johansson, it seems to have rubbed Stewart the wrong way.

According to Sun Times, Stewart is not too happy with the onscreen pairing simply because of ScarJo's reputation of being a "man eater". Though fans of Kristen Stewart may say otherwise, Jeremy Renner of "The Avengers" has said Scarlett has been nothing but professional with regards to their onscreen relationship.

Does Kristen Stewart have anything to be afraid of? Robert Pattinson has laughed the rumors off and did say that he had worked with countless gorgeous women, Reese Witherspoon included, without falling in love with neither one of them. The only woman Pattinson has obviously fallen head over heels for is no doubt, Kristen Stewart.

Still, after Stewart finally calling Pattinson her "boyfriend" in an interview, one can say the 22-year old actress is most definitely possessive. However, Kristen who has a few awesome assets herself would not strike fans as the jealous type. Yet, fans of the "Robsten" couple might want to keep their eyes glued to Scarlett Johansson and Robert Pattinson once filming for "Hate Mail" does begin.
