In a strange social media tirade on Thursday, Kanye West attacked Josh Kushner for his investments in Kim Kardashian‘s underwear brand and tacked on a dig at his brother Jared.

In an Instagram post that received more than 100,000 likes, West wrote, “F—K JOSH KUSHNER.”

Prior to the acrimonious split between Kardashian and West, Kushner’s company, Thrive Capital, made investments in Kardashian’s SKIMS throughout the course of numerous financing rounds beginning in 2020.

The money that Thrive invested in SKIMS was interpreted by West as a criticism of his now-divorced wife.

He prompted Kushner to consider what would have happened if West had bought into his supermodel wife Karlie Kloss’ underwear line.

“WHAT IF I HAD 10% OF KARLIE KLOSS UNDERWEAR LINE WITHOUT YOU KNOWING,” West added in the Instagram post. “AND YOU ONLY HAD 5%.”

Although it’s unclear what exactly Thrive holds in SKIMS, Kushner’s company most recently took part in a January 2022 funding round that valued the business at $3.2 billion, according to Reuters. West apparently holds stock in SKIMS as well.

A Thrive Capital representative declined to comment. Additionally, the venture capital firm invested in Instagram, Robinhood, and Slack; in September, former Disney CEO Bob Iger joined the business as a venture partner.

After attacking Josh Kushner, West attacked Jared Kushner, a former key counsellor in the Trump administration.

According to West, “JARED WAS HOLDING TRUMP BACK.”

The rapper also highlighted the apparent reference to Ivanka Trump, Jared Kushner‘s wife, writing: “IVANKA IS FIRE.”

West and Jared Kushner were last seen dining together in January, so it’s unknown what caused their current falling out. Kanye and Kushner have been friends for ten years, Kushner stated to Fox News in 2020.

In recent weeks, West has been on an Instagram rampage, attacking celebrities including Kim Kardashian, Adidas, and Louis Vuitton Moet Hennessy CEO Bernard Arnault.
