TMZ reported the news in September, claiming the reality star was three months pregnant - meaning she will have her baby around March or April.
Khloe "conceived naturally" - after previously undergoing fertility treatments with ex-husband Lamar Odom.
Khloe's estimated fortune is around £18.5million. Over the past two years, Khloe has dropped a massive 40lbs from her intensive exercise and careful diet.
Khloe confirmed she is expecting her first child with boyfriend Tristan Thompson.
It came after months of speculation regarding her pregnancy, where she refused to confirm or deny the rumours.
But the following year, in December 2016, Khloe and Lamar's divorce was finalised.
Khloe has amassed a fortune through appearing on Keeping Up With The Kardashians, endorsements, modelling and public appearances.
Khloe has also starred in spin-off shows Kourtney And Khloe Take Miami and Khloe & Lamar - plus her more recent talk show Kocktails With Khloe that got cancelled in 2016.
Nowadays she is regularly photographed for glamorous shoots, and interviewed about her amazing physical transformation, though she's also brought out her own line of jeans for "curvy" women.
Born on June 27, 1984, Khloe Kardashian is a 33-year-old American reality star, socialite, model, businesswoman and entrepreneur.
She was raised in Los Angeles and shot to fame in 2007, along with the rest of her family, when Keeping Up With The Kardashians began on US telly.
