Kylie Jenner surprised the world on Sunday by announcing the arrival of her first child -- a baby girl -- with a short statement on social media followed by an 11-minute video on YouTube documenting her pregnancy.
The video reveals a lot about Jenner's top-secret journey to motherhood, which she remained silent on for nine months until she gave birth last week, and it features appearances from every single one of her famous family members -- except for one.

Kylie's father, Caitlyn Jenner, doesn't appear in the video at all, save for archival footage taken from the delivery room in which ex-wife Kris Jenner gave birth to Kylie in back in 1997 when she went by Bruce. You can hear her voice in the clip, and that's it.
On top of that, the former "I Am Cait" star wasn't even in the country when Kylie gave birth to her first child on Thursday, February 1 at Cedars-Sinai Medical Center in Los Angeles. She was in Ireland at the Xposé Benefit Awards, where she won the Beauty Icon Award.

The development is certainly a surprise, but not entirely shocking. Despite intense animosity between Caitlyn and the rest of their family, Kendall, Kylie and Caitlyn have shown no public signs of a feud. After all, they're Caitlyn's only two biological children in the Kardashian clan, and they've frequently expressed a desire to maintain a relationship with their father on "Keeping Up With the Kardashians" -- regardless of where she stands with Kris, Kim, Khloe and Kourtney.

Caitlyn hasn't been shy about criticizing her ex-wife in the press and in her tell-all memoir, The Secrets Of My Life, in recent years, which has caused a very public rift between her and her stepchildren, who have stood by Kris in the feud.
Caitlyn Jenner has yet to acknowledge daughter Kylie Jenner's newfound motherhood on social media, either.
