It might be an understatement to say Khloé Kardashian's relationship with her estranged husband, Lamar Odom, is complicated.
The two hit yet another roadblock this weekend, when the former NBA star was spotted at a bar reportedly ordering alcohol, but the 31-year-old reality star is opening up about how she dealt handled a different complication: introducing Lamar to Caitlyn Jenner.
"When he had his accident and he was in the hospital, Caitlyn was like, 'I want to come and see Lamar,'" the Kocktails With Khloé host reveals in a clip from Wednesday's episode.
"Lamar did not know about Caitlyn at that time."
"Lamar was in a coma and Lamar was in a hospital for four months and I kept Lamar very sheltered," she recalls of the 36-year-old athlete being put into a medically induced coma after he overdosed at a brothel in Las Vegas last October.
"During that time was when Caitlyn was transitioning, but also, prior to Lamar's accident, Lamar was not in the best state. I wasn't there to see him, but I can't guarantee you he was watching television was my point," she continues.

"So, when Caitlyn wanted to come and visit Lamar for the first time was in the hospital, I wanted to respect Caitlyn being Caitlyn, but I also was like..." Khloé trails off, when guest Pauly Shore chimes in, "This is why you guys have the number one show."
A source tells ET that the meeting ultimately occurred "a little less than two months" after Lamar returned to Los Angeles.
"I'm not sure if he entirely understood what was going on, but Lamar is very open and non-judgmental," the source explains. "He would be open and understanding regardless."
Khloé also states in the episode that she is "not still with Lamar," and claims it's been years since the former couple has been intimate.
"I love Lamar, as a person. But I haven't been with Lamar. I haven't been sexually-- I haven't kissed Lamar in years," Khloé, who split from James Harden earlier this year, says. "But do I love Lamar, and do I always want the best for Lamar? 100 percent. Because I don't believe that you marry somebody and you just cut them off."
Meanwhile, as Lamar's sobriety comes into question after he was seen at a bar in Sherman Oaks, California, a source exclusively tells ET that Khloé will "walk away for good" if Lamar continues drinking.
