NEED TO KNOW

Khloé Kardashian participated in her ex-husband Lamar Odom’s new Netflix documentary to reflect on his 2015 overdose and how she helped him recover
In an April 15 podcast episode, she reacted to how Odom has spoken about her since the doc was released and said she’s “pissed that I’m even involved”
She said she thinks her ex “wasn’t expecting this response [to the doc] and now he’s trying to sort of slander me a little bit, which frustrates me”

Khloé Kardashian is firing back at her ex-husband Lamar Odom after she appeared in his new documentary “as a favor” to him.

Odom revisited his 2015 near-fatal overdose, where he was found unresponsive at a brothel outside Las Vegas, in Netflix’s Untold: The Death & Life of Lamar Odom.

Kardashian, 41, appears in the series to speak about her marriage to Odom and how she took care of him in the aftermath of his overdose, including calling off their initial divorce proceedings to be by his side during his recovery.

After the doc’s release, though, Odom, 46, has disputed several of the claims his ex-wife made, including that his dad, Joe Odom, said to not put the NBA player “on life support,” which Lamar said he couldn’t see his dad “ever, ever doing,” and attributing his recovery to God rather than saying Kardashian helped save his life.

On the April 15 episode of her podcast, Khloé in Wonder Land, the mom of two reacted to what her ex has said about her after she “spent hours doing this documentary as a favor.”

“I think what’s pissing me off is, we did this, all good. I was done with this. I’m like, I’m never going to do another Lamar thing again, ’cause I’m all good. But now Lamar is doing press [and saying he’s] annoyed with me. Claiming or insinuating that I’m a liar, all these things, discrediting me, saying that I wasn’t the one that helped him,” she said, referring to what he said on the Today show on April 6.

“I feel so dumb,” Kardashian said, admitting that she’s “pissed that I’m even involved.”

She was asked by Odom and his team to participate in the doc, she said on the podcast, and was “contemplating” it for months before agreeing. “I said, ‘I want to make sure this is a positive piece. I don’t really want to go down this road if it’s negative. He’s been through enough.'”

“Everyone was like, ‘No, it’s amazing. It’s going to be really positive. He’s the one doing it. He’s the one asking,'” she recalled. Netflix then told her they couldn’t “finish [the doc] without [her],” so she agreed to participate.

“I willingly do the Netflix thing for Lamar. I’m not getting paid one penny to do this. I have no dog in this fight. It doesn’t matter to me if this documentary is made or not made. I don’t care. And it’s also not something I really want to talk about anymore.”

“All I did was tell the story that I was asked by you to tell, but now to, like, play in my face and now to act like I didn’t do any of the things I did and insinuate I’m a liar is crazy,” she said. “I feel played.”

Reps for Lamar and Netflix did not immediately respond to PEOPLE’s requests for comment.

“Do people think I like talking about this all day long? No, it’s traumatic,” the Good American founder said of her reliving the marriage and Lamar’s addiction for the documentary. “I would never expose someone that was not for me to expose. I kept all of that to myself for 11 years, or whenever that was. I was asked by Lamar to do this documentary. I did it for him.”

From where she’s sitting, Kardashian said she thinks her ex “wasn’t expecting this response [to the doc] and now he’s trying to sort of slander me a little bit, which frustrates me.”

“For years, he was singing my praises, all this. I don’t even need you to sing my praises. But you’re not now going to s— on me or now play in my face because you don’t like the reaction and the response from the public,” she said.

Untold: The Death & Life of Lamar Odom is now streaming on Netflix.
