Stewart's co-star in the 2002 film "Panic Room" has penned a lengthy essay reflecting on the plight of Stewart, who lately has been embroiled in scandal after admitting to cheating on her boyfriend and "Twilight" co-star Robert Pattinson with her "Snow White and the Huntsman" director Rupert Sanders.
The take-away message from Foster's essay? The invasion of privacy created by tabloid and paparazzi culture can be a soul-crushing experience for a young actor, and Stewart's personal life is nobody's business but her own.
In the essay, published by the Daily Beast on Wednesday, Foster criticizes what she calls "the gladiator sport of celebrity culture," adding, "if I were a young actor today I would quit before I started."
Blasting those who have become obsessed with Stewart's entangled love life, Foster writes: "Just to set the record straight, a salary for a given on-screen performance does not include the right to invade anyone’s privacy, to destroy someone’s sense of self."

Stewart 'fessed up and apologized for the dalliance with Sanders last month, shortly after Us Weekly published pictures of the two of them canoodling.
"I'm deeply sorry for the hurt and embarrassment I've caused to those close to me and everyone this has affected," Stewart said in a statement. "This momentary indiscretion has jeopardized the most important thing in my life, the person I love and respect the most, Rob. I love him, I love him, I'm so sorry."
