Kim Kardashian West thinks "all" of her family will be billionaires one day

Asked which member of her family she thinks could be the next billionaire, she told TMZ: "All of us."

And Kim - who has children North, seven, Saint, five, Chicago, three, and Psalm, 23 months, with estranged husband Kanye West - feels lucky to have passed the monetary milestone.

Asked how it feels to be a billionaire, she said: "It feels blessed".

According to Forbes, Kim's wealth came from her businesses, KKW Beauty and SKIMS, as well as cash from reality TV and endorsement deals,

The 40-year-old star's worth increased from $780 million last October to $1 billion after she cashed in on KKW Beauty by selling 20 per cent of the business to Coty for $200 million.

Kim's half-sister, Kylie Jenner, had been given the title of the world's youngest self-made billionaire by Forbes in 2019 but had the title removed after the publication claimed that she "inflated" figures about her business affairs.

Kim previously defended her half-sister on the issue, claiming that Kylie hasn't had any of her success "handed" to her after her appearance on the cover of Forbes' America's Richest Self-Made Women issue prompted ridicule from some of her critics.

She said: "You know, everyone has a team, I don't care who you are. But when you don't get it from someone else, that's 'self-made.'

"She made her own money for over a decade, she put it in the bank, she saved every nickel.

"And then, when she decided on what she wanted to do, she spent her money on a venture that could have gone south or north, and it did really well."
