Taking to Instagram, the grandmother, 62, shared a hilarious post which included her daughter Kendall Jenner repeatedly saying "baby", in celebration of all THREE of the new Kardashian kids that have been welcomed into the family this year.
"BLESSED!!! #Repost @wmag・・・When three of your sisters give birth in under a year. Congratulations to @KhloeKardashianon welcoming another girl to the KarJenner clan," she regrammed W Mag's hilarious post.
As reported earlier this week by WHO, The Keeping Up With The Kardashian's star's mother flew to Cleveland to be by her pregnant daughter's side during labour.
Khloé and her boyfriend Tristan welcomed their baby on April 12 according to reports by E! News.
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.
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.
The rest of the Kardashian Klan are yet to respond to Khloé's new bub.
