Khloe attends Labour Day bash sans Lamar

Socialite Khloe Kardashian attended singer Katy Perry's Labour Day house party without hubby Lamar Odom.

The 29-year-old instead brought along two of her girl friends. She was also spotted wearing her wedding ring Monday, reports eonline.com.

Khloe wore a pair of shorts, black Timberland boots and a flannel shirt tied around her waist.

Khloe and Lamar have been caught in media speculation that their marriage is on the rocks due to the basketballer's substance abuse issues.

Meanwhile, Perry, the hostess, rocked the party in a crop top and shorts with a sunflower print.
