Khloe Kardashian shocked her sisters when she revealed her cheating ex, Tristan Thomas, has agreed to be a sperm donor to help her get a second child.

In a preview for the show Khloe, who has been undergoing IVF, spoke to her sisters about her egg retrieval.

She explained: “I’ve been doing hormone injections for about five days. And the injection process has been fine. I don’t know why I’m like, ‘Oh, okay, it’s not that bad’,

“Dr Huang was saying that the bonus of doing embryos, you get to see, like, what are your stronger embryos, which are healthy, you get to already know all that…

“Which, I do have a sperm donor, but…” She then explained that she would be using her ex.

Kendal, who was initially shocked, said: “I thought you, like, went to a bank.”

Khloe then explained: “He has to sign, like, legal paperwork that he would just be my sperm donor. But you never know, like, what in three years if I get married to someone? 

“And I’m like, ‘You know what, I don’t want that.'”

Explaining how the conversation went with her ex, she said: “After my doctor’s appointment, I talked to Tristan. Because if you can create embryos and do all the DNA testing, I do think that’s the smarter choice,

“But it’s weird because Tristan and I, we’re not together. I don’t know which way to go.”

In a previous episode of the show, Khloe spoke to Tristan, saying: “I might get some embryos and get a sibling. I might need to borrow some sperm or get some from you…we’ll figure that out later. That’s a whole other episode.”

Well, I guess we’ll soon find out which way she decides to go! Either way, hopefully it’s all a smooth process for the celebrities.
