Khloe Kardashian had never met husband Lamar Odom's drug addict dad until he turned up at her book signing and has the video sneak peek of that moment, to air in E!'s aptly entitled, Khloe and Lamar.
"I've never met Lamar's dad," Khloe, 26, revealed during Joe Odom's unannounced visit.
"Lamar and his dad have a strained relationship but Lamar does still support his father: he pays his rent, gives him a monthly allowance."
Said Joe, "I appreciate everything you guys are doing. You pay my rent, that's a beautiful thing."
Khloe and Lamar airs on Sunday at 10 p.m. (EST) on E!
