Nori’s Black Book pretends to be written by Kim’s eldest daughter North West as it routinely makes fun of the family, even the plus ones such as Scott Disick, and has almost 1M followers.

The page was launched in 2013 and has become beloved for its snarky comments, especially the digs at Kim who is in the process of divorcing Kanye West.

The clips opens with Khloe in a white top and black blazer as she adds massive silver hoops and very long nails; her hair is in a semi top knot and she has on neutral makeup.

They think it could be Jen Atkin.

‘It’s something she’s so capable of,’ Khloe shares. ‘It’s so accurate, it just has to be someone in the circle.’ 

‘Are you behind Nori’s black book,’ she asks Atkin during Facetime as the hairstylist says no and adds she wishes she were that funny.

‘I f***king wish I was Nori’s Black Book!’ Jen states. ‘My captions aren’t that good.’

‘Me and Cece we 100 percent thought it was you last night,’ she added.

Jen says, ‘You know who I think it is?’ and Khloe quickly says, ‘Who?’

‘Steph,’ says Jen.

‘No, I would die if it was Steph,’ says Khloe as Kim says yes she would die too then looks at her cell phone.

Not Jen: They think it could be Jen Atkin. 'It's something she's so capable of,' Khloe shares. 'It's so accurate, it just has to be someone in the circle.' 'Are you behind Nori's black book,' she asks Atkin during Facetime as the hairstylist says no and adds she wishes she were that funny

Kim is in a striped tank top dress with blue slides on. Her hair is half up in a fountain spout and heavy black winged eyeliner as she sits back on a white sofa.

The SKIMS founder adds a gold nameplate necklace.

They next call Steph, who is Stephanie Shepherd.

‘I am calling her right now,’ says Kim as Steph pops up on the screen.

‘We have a serious question to ask you, are you Nori’s black book?’ asks Kim.

Steph, who is a white tank top, says she wishes she was behind Nori’s black book. ‘Oh my gosh, I wish I was f**king Nori’s Black Book!’ Stephanie says.

‘Why is that everyone’s answer?!’ Kim marvels.

Then Steph says she doesn’t think the writer is any of the Kardashian friends because none of them are that funny, no offense, she adds.

Khloe agrees and says no one is that funny and if they were, ‘I’d hang out with them all the f***ing time.’

Next they call Tracy Romulous. ‘I feel like she could help us,’ says Kim.

Then in a confessional Kim says she called Tracy and adds Tracy always knows what to do.

When Kim – who once said she wanted to be a private investigator – asks Tracy is it’s her she laughs.

‘Why don’t we try to contact them and says we want to send them KKW products,’ she said and added they can get a press box.

Kim shares that then they will get the person’s home address and they can find the identity from there.

‘If this works, we’ll finally get our answer,’ says Kim.

A smart idea: Tracy has some good advice: 'Why don't we try to contact them and says we want to send them KKW products,' she said and added they can get a press box

In a hilarious turn, Nori’s Black Book shared the KUWTK teaser with Kim and Khloe on Tuesday.

‘Uh-oh! Mommy and Auntie KoKo are trying to figure out who is “Nori’s Black Book”. They asked everyone they know, even Mason. Do you guys have any guesses??? Tune into Thursday’s episode of @KUWTK on @eentertainment to find out who is behind “Nori’s Black Book”! #KUWTK #Ad.’

This means the identity of the person behind NBB will be revealed.

Before that, the posts were some of the best. A post from Monday showed North giving Khloe a bunch of Baby’s Breath flowers. The caption was funny. ‘I heard Auntie Khloe needed a win, so I had the Malikas pick these up. Look, it was last minute and this was all that was left at the store . I’m not going to call Jeff Latham for her. She’s not my mom. It is what it is.’

A Mother’s Day post from North won laughs: ‘Happy Mother’s Day, Mommy! This past year has come with a lot of changes for you: We decided to stop filming KUWTK, you and Corey turned 40, and Ms. Jonathan got highlights. You’ve handled it all such grace and class. Thank you for all that you do and my check from our SKIMS collaboration bounced. Please call me.’

New episodes of the final season of Keeping Up With the Kardashians air Thursdays at 8:00pm ET/PT on E!
