Kardashian gave birth on Thursday, just two days after news broke that her 27-year-old boyfriend had been allegedly photographed and videotaped with a number of different women throughout her pregnancy.

The 33-year-old’s momager Kris Jenner was the first member of the famous family to publicly congratulate Kardashian on the arrival of her little one, sharing a throwback video clip of daughter Kendall Jenner repeatedly saying the word “baby.”

Kylie Jenner, who’s also a new mom to 10-week-old daughter Stormi, went on to celebrate the happy news by sharing a photo of a long, winding road with a pink filter and the words, “Kongrats, Khloé! It’s a Girl!”
