According to E! News, The Keeping Up With The Kardashians star has welcomed her first child, a baby girl, with boyfriend Tristan Thompson.
A source confirmed the happy announcement to the news site, however at this stage no other details are immediately available.
While this is a joyous occasion for the reality star, it comes after a tumultuous few days – as previously reported by WHO, Tristan has been involved in a cheating scandal, which Khloé is yet to comment on.
The newest Kardashian baby is the first for Khloe but will join Tristan's one-year-old son Prince, who he shares with his ex-girlfriend.
Khloe, 33, announced the gender of her daughter in March during an episode of Keeping Up With The Kardashians.
In September last year, fans speculated about her pregnancy and sure enough the 33-year-old took to Instagram in December to confirm that she and her NBA player boyfriend were expecting their first child together.
