Not shy! On Friday it seems Kim Kardashian wanted to show off her bodacious behind to the world once again

A fluorescent yellow g-string is barely visible, while there is also a sliver of her matching sleeveless crop top.

Though her face is not visible, her raven tresses appear quite wavy and take up most of the frame.

Her enigmatic caption read simply 'say good night and go...'

Later, she also added a quick clip of her receiving a very futuristic hair style to her Instagram story.

Meanwhile, it seems Kim got into a giggle fit alongside sister Kylie Jenner earlier in the week.

The siren was pranking her mother Kris Jenner, 62, when taping an interview for Keeping Up With The Kardashians, as seen in a new teaser for the show.

Mrs Kanye West could not help laughing when the momager fell for it.

Kim rang up her mom on her cell phone during her sit down with Kylie for the KUWTK cameras.

She told Kris, who has been feeling ill lately and thinks she is being poisoned, that Kourtney Kardashian is the one who has been poisoning her.

The KKW Beauty mogul said that Kourtney has secretly been giving the TV producer gluten free 'organic drops' that are making her ill.

'We figured the whole thing out,' says Kim.

'What'd you figure out?'Kris asks.

'That Kourtney has been poisoning you this whole time,' Kim reveals.

'Stop. No way! I just was with her. Why would she do that?' Kris asks.

'Just because she's, you know, has been trying these new all gluten-free organic drops and we think that she's been adding these things to our food,' Kim says.

Despite Kim's chuckles, Kris seems to believes her daughter's crazy confession.

'Stop. She's insane,' Kris says. 'Well, you know she made me throw away all of my Tupperware. She must be doing the drops to reverse the process.'

And that has made the matriarch sick.

Kris falls for it and says that's interesting.

That is when Kim loses it, laughing it up as she says she doesn't want to cry because it would ruin her makeup.

Kylie, 21, also starts to laugh and seems to enjoy the prank as much as Kim does.

Kim and Kourtney Kardashian, 39, were also there and seemed to think their mother was going overboard.

The momager and her two kids are seen in a kitchen.

Kris complains she just isn't right these days. 'I just don't feel well,' Kris tells daughter Kourtney. 'And I don't know if there's something wrong with my drinking water.'

Kris decides to compare the drinking water at Kourtney's house to hers using an at-home water test.

'What does it mean?' Kourtney asks. 'Well exactly, what does it mean is the question,' Kris answers.

'Ideal is where?' Kris asks. 'Seven point six. So yours is seven point two,' Kourtney says.

But her water passes the test.

Who wants to hurt Kris? 'Well, if somebody's poisoning me, I'm gonna get to the bottom of it,' Kris states

'They're slightly different in coloration, but within drinking limits. So, we can rule out the water and back to the drawing board,' Kris reveals.

Now Kris wonders what could be doing it.

'Well, if somebody's poisoning me, I'm gonna get to the bottom of it,' Kris states.

Kourtney then says if her mom is sick no one can tell because she looks so good.

The same day the clip was released, Kim told E! News that she has lost 20lbs and is down to 116lbs thanks for body building and eating much less sugar.
