Kristen Stewart Insulted After 'I Love Rob' Message Left On Her Dirty Pickup Truck (PHOTO)

Now this is not funny ... well, it is a little bit.

Kristen Stewart looked insulted after arriving back at her car to discover an "I Love Rob" message written on the hood. (Obviously referring to her ex-boyfriend, Robert Pattinson). In pictures on X17online.com, the 23-year-old "Twilight" star can be seen staring at the harsh words left on her dirty pickup truck -- most likely a prank pulled by a fan or a paparazzo.

There also appears to be a parking ticket on her windshield ... yikes.

Stewart and her longtime on-again-off-again love Pattinson, 27, split in mid-May following a tumultuous relationship. It was just last summer when Stewart was caught cheating on Pattinson with her "Snow White and the Huntsman" director, Rupert Sanders. Although the couple rekindled their romance for a bit, the scandal was obviously too much for Pattinson to bear.

According to E! Online, the actor is "in a good place" following the breakup, while Stewart is reportedly "heartbroken."
