Khloe Kardashian has revealed sister Kim Kardashian was the one to break the news of Tristan Thompson's paternity test.
The 37-year-old was dating the basketball player when he cheated on her with fitness model Maralee Nichols.
The sports star, 31, had originally denied any relationship with Marelee, but in January a DNA test proved he was the father of her son.
And Khloe has now opened up on how she found out she had been lied to by the dad of her daughter True, four.
Speaking to USA Today, Khloe said it "was hard" to discover the heartbreaking truth of her man's infidelity.
And it wasn't just hard on Khloe, as Kim didn't particularly find it pleasant either.
The SKIMS founder added: "I think that was hard for me, too,” saying she had to tell her sister while they were filming a workout session for new show The Kardashians.
"Déjà vu," Khloe jibed in reference to all the other times the basketball star had been caught being unfaithful during their relationship.
She continued: "I think the first time it was either Kendall or Kylie [Jenner] that called me. Now it’s good old Kim."
Khloe, who co-founded Good American, said the pain "doesn't get easier" but she insisted she has started to become "more numb" to such revelations.
She explained: "When you’re hurt so many times — your reactions, your responses to the same thing happening over and over again — there is a numbing sensation to it."
Older sister Kourtney, 42, admitted that Tristan's behaviour had unfortunately become a "normal" thing but insisted "it should absolutely never become normal".
Earlier in the week Khloe was caught out photoshopping daughter True into Disneyland snaps.
She was left red-faced after fans pointed out she had photoshopped her daughter True into pictures taken at Disneyland, with niece Chicago.
Khloe admitted to doing so after conspiracy theorists claimed that four-year-old True was photoshopped over Kylie Jenner's daughter following Travis Scott's Astroworld controversy.
In a reddit thread, fans were discussing how strange it was for Khloe to edit True into the snaps.
One person wrote: "Yes! It was Chicago and "True" at Disney, but True was really Photoshopped over Stormi. The plot thickens. This is the most konfusing konspiracy in my opinion."
Khloe went on to hold her hands up and admit to editing the picture. She replied to a fan on Twitter : "Welllppp I f***ed this one up. Anyways….. let's focus on something else. Our show airs in a few days."
