A trip down memory lane.

Lamar Odom is getting "emotional" reliving his and Khloe Kardashian's E! reality series Khloe & Lamar.

E! is currently airing an every episode ever marathon of Keeping Up With the Kardashians and all its spin-offs leading up to the final season premiere later this month, and the basketball star happened to come across some old episodes that made him very nostalgic this week.
