Not her usual choice of lingerie! Kim Kardashian's reputation as a sultry sex siren suffers a blow as Scott Disick walks in on her wearing huge pregnancy pants

She's built herself a multi-million dollar empire based on her image as a smoking hot goddess who can bring men to their knees with a mere glance.
So the last thing you'd expect to see Kim Kardashian wearing is a pair of giant, flesh-coloured Spanx pants.
But that's what viewers of Keeping Up With The Kardashians saw on Sunday night's episode.

Some things should stay covered up Kim: No-one needs to see your fat pants, especially your brother in law

Even the usually brazen Scott Disick looked embarrassed as he was confronted with his pregnant sister-in-law flaunting some seriously unattractive underwear.

'Relax, they're like bike shorts - they're like nude colored bike shorts,' Kim assured him as he averted his gaze.

'I get it - I just feel like your voluptuous pregnant body shouldn't be in bike shorts maybe around people,' Scott told her. 'I mean there's a lot going on…'

Kim made it clear she struggled with her bigger pregnant self, telling him: 'If anything it's like less attractive than like my skinny, toned, amazing - can we just reminisce for one second?'

And after Scott insisted she may 'get thinner' after the birth, she admitted: 'I don't think that I am.'

Scott got even more of an eyeful as Kim finally sat up in bed - showing plenty of cleavage in her low-cut top.

'Your boobs are getting a little big - there's a lot going on her for me to look at, it's very uncomfortable,' Scott told her, laughing as she finally got up and put some jogging trousers over the Spanx.
No wonder that Scott's partner and Kim's sister Kourtney was getting a little ticked off with the pair of them.
Tensions were high between the three as Kourtney accused Scott of doing little to help her when she was pregnant with their two children Mason and Penelope.
Scott was even seen playing the perfect father figure helping Kim put together baby equipment and even enthusiastically attending a baby CPR class with her without telling Kourtney.

'It's definitely odd that Scott won't lift a finger around the house but he's jumping up to help Kim with anything that she needs,' she complained early in the show, her fears growing throughout the episode, especially as Scott stopped telling her when he was with her sister.

Even Kim admitted Scott was acting 'so weird' by not being honest about the time he was spending with her, saying: 'It makes it look shady. We're at a CPR class - there's no reason to lie.'

Scott instead his wife should be thrilled, not jealous.

'I'm just trying to be helpful - and I'm being there for somebody in her family,' he said. 'The funny thing is, if I didn't help her sister I'd be in trouble for that.'

But The jealousy came to a head in front of the rest of the family as they helped Kim prepare her baby room, with mum Kris telling her daughter: 'Kourtney, don't be so jelly. He's just trying to be helpful.'

'Well you can hang out with Scott all you want because I am over it,' she said as she stormed out of the house.

When they finally had a heart-to-heart, Kourtney admitted that her frustration came from seeing him be so helpful now when he 'didn't want anything to do with me' when she was pregnant with their second child.

'I definitely feel that I am a little guilty, that I've been maybe a little more pro-active with helping Kim,' Scott admitted.

He told her: 'The first time around I was there for you more than I was the second time - but I want to be able to try to make it up to you now.

Kiss and make up: Kourtney forgives Scott yet again

'So whatever you need from me I am always here and always on board.

'I want to help you and make our lives smoother than it already is.'

After they kissed and made up, Kourtney admitted that seeing Scott do so much for her sister was something she should actually be grateful for.

Meanwhile, Kim makes the decision to move into her mother's home after learning her house renovations will not be completed until next year.
