"Kongrats, Khloe! It's a girl!" the reality star's Snapchat filter read. It also contained pink balloons.
The 20-year-old Keeping Up With the Kardashians star shared the snap on Thursday while driving around with her BFF Jordyn Woods.
"BLESSED!!!" the momager wrote, crediting W Magazine for the clip. "When three of your sisters give birth in under a year. Congratulations to @KhloeKardashian on welcoming another girl to the KarJenner clan."
