Kim Kardashian officially joins billionaire club

Reality TV star Kim Kardashian has been declared as a billionaire for the first time on Forbes' annual world's billionaires list on Tuesday.

Forbes estimates that Kim Kardashian is now worth $1 billion, up from $780 million in October 2020. All this occurred within only 5 years after Forbes first reported she had made her first $51 million.

The "Keeping up with the Kardashians' star's wealth mostly comes from TV income and endorsement deals, as well as her two lifestyle brands KKW Beauty and Skims, reports Variety.

KKW Beauty was launched in 2017, often releasing cosmetic products in partnership with her four famous sisters that are heavily promoted through social media -- Kardashian alone has 69.7 million Twitter followers and 213 million Instagram followers.

By 2018, the company had been making about $100 million in revenue, according to Forbes, which has listed 2,775 billionaires in this year's rankings.

Her most recent project, Skims, the shapewear line launched in 2019, offered underwear and loungewear in the founder's signature minimalist style, a move that proved lucrative during the work-from-home era.

Though the company -- of which Kardashian owns a majority stake -- has not disclosed revenue figures, Forbes has estimated its worth at more than $500 million.

The rest of Kim Kardashian's fortune sits in cash and investments, including real estate. Every year since 2012, she has earned at least $10 million pretax, by Forbes' count. Moreover, she's got three properties in Calabasas, northwest of Los Angeles, and a portfolio of blue-chip investments, including shares of Disney, Amazon, Netflix and Adidas that her soon-to-be ex-husband Kanye West gifted her for Christmas in 2017.

Jenner, the youngest member of the Kardashian family empire, fell out of the Forbes rankings in 2020 after the magazine claimed the 23-year-old had been inflating the size of her own cosmetic business. She had been named the world's youngest self-made billionaire in 2019 at age 21.
