#Kylie Jenner pregnancy rumors have been circulating since September and despite the "KUWTK" star's absolute silence on the matter, her #Baby Girl has arrived! On Sunday, Kylie posted a message and video to Instagram to let her fans know she had given birth...three days earlier. How she did that, at #Cedars Sinai no less, without even a whisper about it from the paparazzi is remarkable.

Kylie and Travis welcome a baby girl

Just like the Kylie Jenner pregnancy rumors [VIDEO]suggested she would, the lip kit mogul gave birth to a baby girl on February 1. The still unnamed baby girl weighed 8 lbs., 9 ounces and was born at 4:43 pm.

Like the other KarJenner babies, Kylie gave birth at Cedars Sinai, which is why many are so surprised that she was able to go three days without having her birth news broken by a leak, especially after learning just how many people were helping Kylie and Travis keep their secret for the last several months.

Jenner posts a note to fans

Kylie Jenner made a grand return to Instagram on Sunday with a note to her fans. In it, she explained why she decided to keep her pregnancy a secret for the entire nine-month journey. She apologized for keeping fans "in the dark" but said that she did it to keep her pregnancy as stress-free as possible.

Kylie also confessed that pregnancy has been "the most beautiful, empowering and life-changing experience I've had in my entire life." She thanked her family and friends for keeping the secret and helping her to make it through her pregnancy journey with as much privacy as someone as popular as Kylie Jenner could ever expect.

In addition to her note, Kylie Jenner also posted a YouTube video link in her bio. If you haven't seen it yet, it's definitely something that needs to be checked out. From Jordyn Woods explaining how she found out about Kylie's pregnancy at the beginning to hearing the baby girl's first cries at the end, this was easily one of the most personal things that Kylie has shared with her fans. After such a long drought from the reality star, it's safe to say that the emotional 11 and a half minutes was a nice way to let "KUWTK" fans back in to see what she experienced.

There are also Kylie Jenner baby belly [VIDEO]shots in the video, something fans have been dying to see. Not to mention, we got a much closer look at Kylie's relationship with Travis Scott. It's safe to say that the pair looks pretty happy together. And now, their baby girl makes three.
