Kylie Jenner was making around £1 million for every sponsored Instagram post before lockdown began.
The reality TV star, 22, has 173 million followers and regularly uses her account to plug her Kylie Cosmetics and beauty brand.
However, she also posts plugs for other companies, and although these posts are rare - she reportedly earns big bucks for them.
According to data published by Instagram tool Hopper HQ, Kylie earns around $1.2 million - around £960,000 - for each ad she shares.
Her last big plug came in December, when she promoted a range of Frozen II dolls from an online toy store.
She's also promoted SugarBearHair vitamin gummies and Teami Blends wellness products.
Kylie hasn't posted any sponsored ads since her native California went into lockdown during the coronavirus outbreak.
It's not known whether she'll be able to continue to command the huge sums for every post as the pandemic has tanked economies around the world.
However, she's continued to plug her own company in a bid to keep the brand in business during the global crisis.
Last year Kylie was named the world's youngest self-made billionaire by Forbes magazine, mostly thanks to her beauty empire.
She started off by selling lip kits - promoting the brand using her filler-plumped pout - and later moved into cosmetics and skincare.
The reality star pulled it off again in 2020 when the magazine handed her the same title for a second year in a row.
She's just one of 2,095 people in the world with a fortune worth 10 digits.
She sold off a stake of her business to Coty Inc. for $600 million but she continues to a hold a 49 per cent stake in the company which is said to be worth around $1.2 billion.
