Kourtney Kardashian has expressed an interest in nursing her sister Khloe Kardashian‘s baby boy.

On the season two conclusion of Hulu’s The Kardashians, she made the strange admission to her sister Khloe Kardashian, who is the mother of her nameless son with ex-boyfriend and basketball player Tristan Thompson.

“When they open their mouths and just the way they smell,” Kourtney, who has three children with ex and socialite Scott Disick, says before holding the baby in Thursday’s episode.

“Oh, my God, Kourt, let’s calm down,” Khloe responded, laughing.

The youngest family member has not yet been captured on camera, but according to femalefirs.co.uk, he is said to resemble the 35-year-old brother Rob of the two.

Even Kris Jenner, 67, considers naming her surrogate-born grandchild after her son.

In the episode, Kim and Kris can be seen agreeing to the fact that Khloe’s son is “actually Rob [Kardashian]’s twin.”

“How about Rob? How about Rob Kardashian Thompson, and then just call him Rob Kardashian,” Kris said.

Khloe, 38, and basketball player Tristan are the parents of True, 4 years old. Following her IVF procedure, Kourtney decided she wanted to breastfeed.

Although the 43-year-old reality star is eager to start a family with her husband Travis Barker, she felt “pushed” into undergoing fertility treatment. As a result, she is now more realistic about the issue than she once was.

 “I got to a place where I just felt, like, exactly how timing was everything with me and Travis. I feel – truly – like if it’s meant to be, it’ll happen,” she said.

Through a surrogate, Khloé, 38, and Thompson, 31, had their second child in July. By the time the co-founder of Good American learned that the NBA player was covertly expecting a second kid with Maralee Nichols, the couple had already split up.

Khloé’s representative at the time said that she was “very grateful to the exceptional surrogate for such a beautiful blessing,” Page Six reported.
