Kristen Stewart became a victim of a cruel prank after someone left a love message to Robert Pattinson on her car. On Monday, July 8, she was spotted leaving a studio in Los Angeles. In some pictures obtained by X17Online, the actress wore a white t-shirt, a pair of jeans and a backward cap.

The "Snow White and the Huntsman" actress was photographed walking to her car. Kristen approached her blue truck and saw words "I [heart] Rob" written on the dusty hood as she entered her car. The 23-year-old actress, however, ignored the message and drove off.

Kristen and Robert broke up in May following an alleged huge fight around the British heartthrob's birthday. Robert later was seen moving out of the house they shared. "He showed up early in the morning in a big red pickup truck and was in the house for maybe 30 minutes. When he came out, the back of the truck was loaded with stuff. Suitcases, a bike, trash bags full of his things," an eyewitness said.

After breaking up, Kristen and Robert spend their time with friends. Robert recently was spotted driving around Los Feliz area with a mystery woman on his car's passenger seat, while Kristen traveled with her friends and even got a small tattoo on her right wrist.

The "Twilight" actress is currently busy with her latest project, "Camp X-Ray". The movie is about an American soldier who is stationed at Guantanamo. The soldier later befriends an inmate who has been there for a few years. Kristen will play alongside Lane Garrison and Peyman Moaadi.
