The Kardashians are all about business. Kim Kardashian has her billion-dollar KKW Beauty while Kylie Jenner has her $900-million Kylie Cosmetics. Everyone's running something—Khloe owns the denim brand Good American; Kourtney, the lifestyle website Poosh; Kendall, 818 Tequila; and Rob has a luxury sock line called Arthur George.

Imagine how great it must be for Kris Jenner who gets a 10% momager cut from those businesses. She gave birth to an empire. No wonder she doesn't have a brand...that she talks about, at least. Recently, internet sleuths discovered that it's possible Kris Jenner co-owns a water company with one of her daughters' ex.

Kris has never endorsed this brand on her Instagram. It's weird since the Kardashians are known for sponsored posts. At one point they even faced a $5 million lawsuit for misleading "weight loss" ads. Now, this 138 Water is raising suspicions due to its social media campaigns that only feature girls in bikinis, not the product. The rumor is, it's "affiliated with a high-price escort service."

Kris Co-Owns A Water Brand With Kylie's Ex, Tyga

In 2017, the online forum Lipstick Alley discussed a blind item by Crazy Days and Nights. It says: "Last year she was affiliated with a high-price escort service run by a sleazy paparazzi agent (who uses bottled water ads as a catalog of available girls)."

The paparazzi agent is said to be Thibault Mauvilain who's credited for many of the bikini-clad campaign shots. His LinkedIn profile says he's the present Business Development Manager for the company. His header also says that 138 isn't limited to 138 Water — he has "138 Lifestyle Brand" written on it, too.

The description adds: "The so-called 'Fashion Water' is a front company who lists this always broke rapper as a spokesman and co-owner." There was a press release about Tyga's signed partnership with 138 Water in 2017. In 2016, Radar Online revealed that the rapper had secretly filed for bankruptcy in 2010.

"A real co-owner is this momager herself," wrote Crazy Days and Nights. "Most if not all the models posing in these water company ads are available for a price. Including this sister of this ex-Disney actress turned escort" There are speculations that the celebrity escort is Bella Thorne's sister, Kaili. She did some photoshoots for 138 before.

Suspicious Details About The Brand

"If you enter 138 Water into Google Image search you get a ridiculous number of models," noted a Lipstick Alley user. "All young white women (Kaili being the only exception I know of because she is Hawaiian and Cuban) in bikinis by the shore, with a bottle of water that's barely [noticeable] in the picture and almost an afterthought." How odd.

The Kardashian siblings were never seen carrying a 138 bottled water except for Rob and his ex-fiancé — Blac Chyna, who's also Tyga's ex and baby mama. She did a topless photoshoot for the brand with Mauvilain. Other celebrities like James Franco, Cedric the Entertainer, and Christina Milian were also spotted with the product.

138's Instagram is strangely inactive for a brand page. It won't take you long to see posts from 2019. They're mostly girls in bikinis with the 138 logos stamped on them. You'd have to look closely to see the bottled water in the pictures. They don't have an official website, but they have apparel listings on Amazon and Shopify.

"They're doing the bare minimum to look like a water [bottle] and apparel company," said someone on Reddit. As of now, there's no confirmation of Kris Jenner's association with 138 or what it's really about. Mauvilain and Tyga are probably to blame for those offbeat ads.
