Khloe Kardashian left the gym in L.A. this morning, and the reality star didn't disclose any information when asked about her brother Rob, who has vanished from the public eye in recent months amid reports he's depressed.

Kris Jenner clearly doesn't realize how sensitive the mental illness subject is either, because she shared an encouraging note on social media with her son today, and it all but confirmed his recent struggles. "You were never created to live depressed, defeated, guilty, condemned, ashamed, or unworthy," the image read. Way to keep things private, Mama K!

We don't blame Rob for wanting to distance himself from his famous family!
