'Robsten' Update: Pattinson Pissed at Stewart for Wearing His Clothes

A breakup can be messy: from the deleting in Facebook, returning of things, maybe even the burning of sweet photographs. A celebrity breakup, however, is an entirely different thing. And after the scandal that Kristen Stewart recently starred in, she is learning this bittersweet reality the hard way.

Sources say that Robert Pattinson is less than impressed at seeing photos of Kristen Stewart wear his old stuff which included his backpack, hat and his ring.

Is this Kristen's futile attempts in showing Rob that she is still thinking about him?

"He's been doing his best to push through this, promoting his movie and everything while still trying to figure out where he and Kristen stand. With these photos of her wearing his hat, backpack and ring, it's just got him wondering what kind of mind games she's playing." said Radar Online as reported by Hollywood Life.

The two "Twilight Saga" stars broke up after the 22-year old was photographed by the paparazzi sharing an "intimate moment" with her "Snow White and the Huntsman" director, Rupert Sanders. Robert Patinson, 26, always said that he would not tolerate cheating in a relationship, and in this instance, he was truly a man of his word. Since then, Kristen has been rumored to try and get back together with Rob.

Will this cause tension between the two co-stars and ex-lovers during the premiere of the epic conclusion of the Twilight Saga known as "Breaking Dawn - Part 2"? Fans are speculating that the two will not appear on the red carpet, but reports says otherwise.

"[Rob's] told movie bosses he'll walk the red carpet to save her from embarrassment and any female fans booing her. He is being professional and taking the higher moral ground," continued Hollywood Life, as said by a source to The Sun.

Despite this, the "Cosmopolis" star is still unsure of where he stands between the relationship.

Fans may be delighted to know that they will see "Bella and Edward" together walking the red carpet during the premiere, but then again, how will Kristen Stewart carry herself, knowing that she will be walking with the guy he cheated on? Fans will just have to wait for the premiere.
