Khloe Kardashian still stresses out over Lamar Odom.

The reality star feels pressure to keep her estranged former NBA pro husband safe in a new clip from Sunday's Keeping Up With the Kardashians, where Lamar gets set to make his first public appearance at Kanye West's Yeezy Season 3 fashion show and album release party.

"You're just chilling, right? You don't have anxiety, only I do," the 31-year-old tells Lamar. "I know you wanna go, but it's a lot."

While Lamar tells Khloe that he understands her apprehension, she admits during a taped confessional that she wants Lamar to be able to take this step.

"At the end of the day I want Lamar to be happy," she explains. "I still feel a ton of anxiety and pressure, but if this makes him happy, and I can keep him safe, then that's a match made in Heaven."

Khloe has been very protective of Lamar after the basketball player was found unresponsive in a Nevada brothel last year, admitting at one point that she kept him "very sheltered" during his recovery.

In another KUWTK clip, Caitlyn Jenner explained that during his recovery, Lamar was initially confused by her transition.

"I know Khloe tried to explain it to him a couple times, but at that point I don't think he was getting anything," the 66-year-old former Olympian revealed.
