Reality Tv star Khloe Kardashian and her sportsman husband Lamar Odom reunited on Tuesday (08Oct13) to rally around her mum following news of her separation from husband Bruce Jenner.

The couple hasn't been seen out in public together for months, ever since reports started swirling about the basketball player's alleged substance abuse issues, but they showed a united front on Tuesday night as they drove out to Kris Jenner's home in Calabasas, California.

The sighting comes just days after Tmz.com reported Khloe is planning to divorce Lamar over his alleged cheating and drug use.

Neither Kardashian nor her husband have officially commented on the status of their marriage, but her mother and stepfather confirmed reports of their own separation in a joint statement released on Tuesday (08Oct13).

The statement read: "We are living separately and we are much happier this way. But we will always have much love and respect for each other. Even though we are separated, we will always remain best friends and, as always, our family will remain our number one priority."

Meanwhile, Odom kicked off Wednesday (09Oct13) by entering a not guilty plea to a driving under the influence charge stemming from his arrest in August (13).

His lawyer, Rich Hutton, entered the plea in court on his behalf.

According to police reports, the former Los Angeles Lakers superstar failed numerous field sobriety tests during the traffic stop and also refused all chemical tests when he was booked.

A pretrial date has been set for next month (Nov13).
