Beating the heat with an icy cold drink, Kristen Stewart and a pal stopped by a Glendale, CA juice bar on Tuesday (July 9).

Donning black pants and a white tank top, the "Twilight" actress seemed in good spirits as she carried her beverage back to her friend's car.

On Monday, the 23-year-old was less than thrilled to see that someone scrawled "I (heart) Rob" on the hood of her dusty truck.

Keeping a somber expression on her face, KStew hopped in her vehicle and drove away in an attempt to ignore the note.
