Kim Kardashian has lunch at Nobu Malibu with philanthropist Laura Arrillaga-Andreessen

Kim Kardashian put her newly slimmed-down figure on display on Thursday for a lunch meeting at the Kardashian favorite Nobu in Malibu.

The 41-year-old looked sleek and stylish in a black bustier-style top while meeting up with the philanthropist Laura Arrillaga-Andreessen for some Japanese cuisine.

Her meet-up came as her ex-husband Kanye West escalated his feud with her and her family on social media following a relatively quiet period since her split from Pete Davidson.

Kim looked sleek and stylish in her all-black ensemble, which included a bustier-style top that highlighted her cleavage and showed off her recently slimmed-down arms and waisted.

She contrasted the top with a more voluminous set of flared pants, along with black platform heels.

The platinum blond beauty, whose raven roots were beginning to show, contrasted her dark outfit with her pale hair, which was tied back in a tiny bun. 

Kim added some luxury to her look with a black Balenciaga hourglass bag with an embossed crocodile pattern, which sells for $2,950 at several high-end retailers.

Kim completed her look with sporty black wraparound sunglasses with large bug-eyed lenses.

Laura matched Kim’s outfit with her own all-black ensemble featured a black jacket and matching leggings, along with chunky alligator-print boots.

She wore round-frame sunglasses and styled her long blond hair down across her shoulders, and she added a splash of color with a bright yellow alligator-print Birkin bag.

The philanthropist is the wife of Silicon Valley entrepreneur Marc Andreessen, and the daughter of the billionaire real estate developer John Arrillaga.

Kim’s brief getaway appeared to happen amid a barrage of deranged Instagram posts from her ex-husband Kanye West, who confessed to having an ‘addiction’ to pornography that ‘destroyed’ his family.

He also lashed out at Kim for her choice of a school for their four children — North, nine; Saint, six; Chicago, four; and Psalm, three — and he even continued his attacks on her mother Kris Jenner, 66.

Kanye seemed to kick off the barrage of posts this week with a fake New York Times front page announcing that Adidas CEO Kasper Rørsted had ‘died’ at 60, though he is still alive.

The rapper poked fun at the CEO’s alleged lack of name recognition, and he joked about not knowing who his former friend Kid Cudi was in small text at the bottom.

He previously broke his Instagram silence with a similar fake newspaper front page to mock Kim’s ex-boyfriend Pete Davidson after their breakup.

On Wednesday, he shared a photo of young children seemingly all wearing black Yeezy clothing to mark ‘The Doves first day at Donda [sic].’

The students were matriculating at his Donda Academy, named after his late mother and his two most recent critically derided albums.

The private Christian school has been described as ‘project based,’ rather than focusing on traditional teaching, though little is known about the school.

But Kanye seems to have developed a desire for his children with Kim to attend his new school, rather than the elite private school Sierra Canyon. It’s not clear if this has been a long-standing desire, or if he is bringing it up publicly now that his new school (which is tuition based) is open to students.

‘My kids going to Donda / They not going to Sierra Canyon / Charlemagne the God [sic] and Kris / get your motherf***ing popcorn,’ he wrote in one post.

In his caption he wrote, ‘Hi Hilary [sic] Hi Mark You gonna take me off instagram :).’

He appeared to be referring to Facebook founder and Meta chairman and CEO Mark Zuckerberg (as Meta owns Instagram), but his reference to Hillary Clinton was more bizarre, as she doesn’t have any meaningful connection to the platform or his current issues. Yet she factored in his subsequent breathless posts.

A subsequent post featured a text exchange that appeared to be with his ex, whose texts he has made a habit of sharing with his 16.5 million followers.

After she appears to write ‘Can u please stop,’ he continues, ‘No. We need to talk in person. You don’t have say so of where the kids go to school. Why you get say so. Cause you half white?’

He captioned it with a popcorn emoji.

Later, he posted a screenshot of a post from Victoria Villarroel and wrote, ‘Don’t let Kris make you do playboy like she made Kyle and Kim do Hollywood is a giant brothel Pornography destroyed my family I deal with the addiction instagram promotes it Not gonna let it happen to Northy and Chicago.’

A follow-up that appeared to be from the OnlyFans model Monica Corgan, whom Kanye has spent time with in the past, featured an exchange in which she said she waned to ‘stop [OnlyFans] and do fashion consulting full time,’ which he captioned, ‘Praise God.’

In an already deleted post, Kanye complained about how his children’s school teaches them about the holiday Kwanzaa.

‘What the f*** is Kwanzaa and who made that bulls*** up,’ he wrote. ‘Everyone lives in LA for the check anyway so no one really cares about their children being indoctrinated.’

He also added in his caption, ‘Let’s see if I can get blocked by Mark again :).’ 

Among Kim’s apparent posts was a plea for him to stop posting about her mother Kris Jenner.

‘From my mom- PLEASE,’ wrote his ex. ‘”Tell him to please stop mentioning my name. I’m almost 67 years old and I don’t always feel great and this stresses me to no end.”‘

The rapper replied,’ Y’all don’t have so so over my black children and where they go to school. They will not do playboy and sex tapes. Tell your Clinton friends to come get me. I’m here [sic].’

In another post, he referred to Tristan Thompson, Travis Scott and Scott Disick as his ‘fellow c** donors,’ saying they were ‘in this 2gthr.’

He also included a screenshot of his Google search for ‘c** doner.’ 

Kanye, who has previously been open about living with bipolar disorder, was confrontational about his current mental state in a post from Thursday evening.

‘Anybody that says I’m spiraling when I express the undeniable truths is a sheep. STFU and worry about your own kids,’ he wrote. ‘I obviously am dealing with wars at the highest levels of control and discrimination based on the level I’m operating at.

‘A conductor gotta turn they back to the audience to direct the orchestra.’ 

He added, ‘Oh Ye crazy Is basic as f*** at this point. I’m simply right. I know girls who sell p**** that don’t agree with how my daughters are displayed.’

He captioned the post, ‘Y’all not finna keep discriminating on me while the organizations use me and use us all.’

Then he added in extra-large text in his next post, ‘I’m the kids father.’

‘Imagine not having any say so where your kids go to school,’ he captioned it. 

He wrote something resembling a poem that alluded to the Kardashians on Hulu.

‘I was driven crazy before / I’m not going crazy no more / It’s not up to Calabasas or Hulu / where my kids go to school / I’m not the crazy one here.’

He continued, ‘It’s up. I won’t stop until I have a say so on my kids no matter what it legally takes.’

The monster rapper added, ‘Come and get me I’m a man of God The fathers job is to be the bad guy some times So Trevor Noah come speak to my family so I can be the bad guy.’

Pete Davidson even got swept up in the bizarre posts.

‘Ask Pete how those tattoos of my kids doing in the trauma unit,’ he wrote. 

Kanye expressed solidarity with fellow rapper — and Kylie Jenner’s partner — Travis Scott by writing his name out as ‘Trav’ and then writing an addition ‘is’ by hand.

He added a ‘Scott,’ presumably for Scott Disick, Kourtney Kardashian’s former partner, who has been left out of recent family functions over his tantrums about her relationship and then marriage to Blink-182 drummer Travis Barker.

He referred to the two men as his ‘brothers,’ just before he suggested they weren’t pulling their weight in his battle against Kris Jenner.

‘These my brothers I’m only on I ever seen stand up to Kris though Come fight me I love pain,’ wrote. 

He summed up his rapid-fire posts in his next one: ‘Today is about control.’

He continued: ‘MY KIDS, YZY ADI, YZY GAP. It’s up on all 3 of these issues. At the same time. Cause It’s all the same mentally that makes these people feel they can keep getting away with things.’
