Kardashian's concern follows a weekend for Lohan, 22, in which she was issued a short-lived arrest warrant and witnessed the arrival of police at girlfriend Samantha Ronson's home on Saturday after a loud disturbance at the home led to a broken window.
"It's so sad that there's such an invasion of privacy, with camera people, cops and paparazzi outside their home," Kardashian, 28, told PEOPLE Monday.
"I mean, when have you not thrown something when you're mad?," says Kardashian. "Everyone has to admit that at one time in their life, they've gotten so mad that they've thrown something, but maybe not necessarily breaking a window."
Can't people have an argument without everyone watching?," asks Kardashian, who recently came to the defense of another star, Jessica Simpson.
Why Blame Lindsay?The Keeping Up with the Kardashians star also scoffs at buzz that Lohan, who has had previous stints in rehab, is spiraling out of control. "Just because she had an argument, I don't think it means that she's off track and that everything is crazy. It's really just messed up that everyone blames her."
Her tips for coping with the scrutiny? "Focus on living your life and not the watchful eye everyone has on her," says Kardashian, who appears in a steamy pictorial with football player boyfriend Reggie Bush in the upcoming GQ. "I think everyone needs to let her breathe."
And as for some motherly advice, Kim's mom, Kris Jenner adds, "[Lindsay]'s got an amazing mom, a beautiful sister and brothers, so just stay close to your family anytime you're having struggles with anything."
"Everyone's concerned about Lindsay," says Jenner, "but leave her the heck alone and let her live her life."
