They Still Have 99 Problems! Khloé Kardashian & Lamar Odom Avoid One Another At Jay-Z Show In L.A.

It's still a hard knock life for Lamar Odom and Khloé Kardashian, as the estranged couple attended this week's Jay-Z concert in Los Angeles separately, RadarOnline.com has learned.

The NBA free agent sat in a private box at the Staples Center, where he's played as a member of both the Lakers and Clippers; while the youngest of the Kardashian sisters, seated in a separate area, wore a sleek all-black outfit -- and had zero interaction with her one-time "Lammy" throughout the evening.

The couple, rocked with scandal the past few months, looks to be in a valley, as they did take in a concert together earlier this fall -- extended family member Kanye West.
