TMZ is reporting

Khloe and Lamar have decided to end their own spin off. The shows second season will be its last.

Lamar only wants to focus on one project at a time and right now it is the NBA after being put on the NBA inactive list by the Dallas Mavericks. He is now living in LA full time and has hired trainers to help him get back in the NBA.

Khloe and Lamar will still make appearances on "Keeping Up with the Kardashians" but that's it for now.
