The 33-year-old reality star was seen constantly taking selfies while on family holiday in Thailand - even telling an assistant in a camera shop it was 'the purpose of life'.
But her obsession reached an embarrassing low when her assistant was taking racy photos of the star in a wet white dress and no underwear - and stepbrother Brody Jenner walked in.
Selfie obsession: Kim Kardashian was embarrassed on Sunday's episode of Keeping Up With The Kardashians when step-brother Brody Jenner walked in on her taking photos in a wet white dress
Making the accidental exposure all the worse, Brody admitted to brother Brandon and his wife Leah that he was slightly turned on by the sight, joking that he got aroused after clearly seeing her naked body through the effectively see-through dress.
'Oh that's sick,' his brother complai
Along with the embarrassing encounter, Kim's obsession with getting photos of herself had already driven sister Khloe mad.
'She is obsessed with taking pictures - totally normal!' Khloe complained sarcastically at her sister.
'We're watching like fire-eating people, it's like a cool once-in-a-lifetime thing to witness, and instead of being in the moment Kim is taking selfies.
'I don't even know - I'm so over the f***ing selfies,' a frustrated Khloe said.
And when she saw the stunning Iniala Resort they were staying in, she excitedly said: 'Every single room has a different selfie backdrop. That is so amazing!'
She then told her assistant Stephanie: 'We have to do, like, one wet shot a day.'
She was taking photos in a skintight white dress that she got wet to show she was wearing no underwear and was telling the assistant to 'make me look skinny' when Brody suddenly walked in and saw almost everything.
'Woah! Woah! Woah! What are you doing?' Brody asked as Kim used her arms to try to cover up. 'What the f***!'
Kim told the camera about the moment: 'This is so embarrassing I want to die, and he's, like, frozen, just shocked. It's just like super awkward.'
As he tells his brother and sister-in-law about the 'extremely awkward' encounter, Leah asks him: 'Did you get turned on by Kim?'
'You got a little turned on by your sister!' Brandon teased his brother from his reaction.
When Brody admitted he did, his brother was left complaining: 'Oh that's sick.'
Kim's obsession with photos of herself also caused tension with her sisters when she excitedly announced she had shot the cover for Vogue magazine - and they joked about it rather than falling over themselves with praise.
'This is like when you're a little girl and you have this fairytale of being princess - it's like the same exact thing,' she said of getting the cover.
