Kardashian fans have been horrified by Kim, Kourtney and Khloe's "creepy" behaviour towards their brother Robert as a clip from their show Keeping Up With The Kardashians resurfaced.
Viewers branded the episode, which was filmed in 2012, "appalling" after watching Kim make a crude joke about their brother's manhood when he was a baby.
The shocking joke saw Kim tell Khloe and her now ex-husband Lamar Odom: "When Rob was really little, he was like a baby, Kourtney and I had to change his diaper once and we would flick his d**k to see what would happen."
While Khloe laughed, Lamar put his head in his hands and didn't seem to find the joke funny.
The clip resurfaced on Reddit, and users soon took to the comment section.
One wrote: "It’s appalling that this made to the show - wtf were they thinking??? I mean we’re they thinking at all?"
Another viewer added: ""This is horrific", while a third chimed: "Why are they always so creepy with Rob."
Others, however defended the sisters. One user typed: "Have you guys been around kids..? Have kids? No offense but there’s really nothing wrong with this. Little kids are curious about their bodies/other people's bodies. It’s not sexual."
Another added: "Kim and Kourtney would've been 6/7 or 7/8 when they did that so I don't think it was anything sexual they were little kids."
It comes after a video of Scott Disick breaking down in tears on the show emerged earlier this week.
The clip, which originally aired in 2016, showed Scott, now 38, and Kourtney, now 42, shortly after they had separated, with him seen apologising to her family for his behaviour.
It opened with Khloé, now 37, recalling Scott used to say he didn't have a family, so they gave him one, with her then asking him: "Why do you like destroy it?
He responded: "I'm sure you guys have heard a lot of horrible things about me that I should have just been honest with, but I was too ashamed that I was gonna hurt everybody."
Scott - who has three children with Kourtney - said he had apologised to her numerous times but had never done the same to her family, including matriarch Kris Jenner, 66.
"I've never apologised to like all of you for letting all of you down and embarrassing you guys," he is heard saying in the footage, understood to have been filmed in 2015.
He says: "I understand I need to help myself way before I can help [Kourtney] or my kids. It's just been a really hard time going from having all of you guys to having nobody."
The resurfaced clip prompted numerous responses on Reddit, with one viewer writing: "This is such a real scene. The cycle of addiction and shame and all that mess."
"This scene was sad, I think Scott believed it when he would say he wanted to change but his self sabotaging tendencies always won out because of his addiction," said another.
