Khloe Kardashian Stays Low-Key Amid Lamar Odom Rumors

Yep, that's Khloe Kardashian, trying to stay low-key despite mounting rumors and concern over husband Lamar Odom's health. The typically camera-friendly reality star was photographed leaving the gym Tuesday in Los Angeles and attempting to cover her face up with a black hooded sweatshirt.

Odom resurfaced earlier this week after the pro basketball player went "missing" over the weekend. People magazine reported that drug use was the source of marriage troubles for Kardashian, who reportedly staged an intervention last week. "They really do love each other," a source for the publication said. "But she really feels that this problem is out of control, and she's hurt that he won't get help."
