Someone pranked Kristen Stewart post-split from Robert Pattinson while she was inside of a North Hollywood studio on Monday by writing the words “I Twilight Saga ex, written on her dirty blue car.

NY Daily News reports Stewart was dressed down in her usual off-screen attire, a T-shirt and teens and a backwards baseball hat.

Stewart and Pattinson broke up in May after an on-again, off-again relationship that lasted four years and was plagued by a cheating scandal last summer involving Stewart’s Snow White and the Huntsman director Rupert Sanders.

Last week it was rumored Pattinson had moved on with Elvis’ granddaughter Riley Keough, who worked with Stewart on 2010’s The Runaways but her rep denied it in a statement.

Keough’s rep told Just Jared, “Riley isn’t dating Rob. And I can confirm that Riley was not photographed at all this weekend.” Pattinson was photographed driving around with a mystery woman, who was thought to be Keough.
