Tokyo also celebrated the exciting day with a picture of her Chymoji face on Instagram and captioned it, "All praises to God!!!!!!!"
Chyna brought two big Louis Vuitton tote bags filled with leopard throw blankets and sheets with her to the hospital! Already their daughter is getting a fashionable welcome into the world!
The couple have shared some pregnancy milestones throughout their journey to the baby's arrival with fans on social media.
The new proud parents sweetly shared the joy they had when they felt their baby move inside of her belly.
"So today I felt my baby move," Rob says in a clip posted on Blac Chyna's Snapchat. "Super excited @robkardashian and I felt our baby moving today," she wrote on Instagram.
Blac Chyna also openly discussed her pregnancy weight on social media and in late October she posted a photo from her doctor's office with the following caption: "Checking on our baby girl! Never knew I'd be so happy about gaining 72 pounds!"
"If you guys are wondering, I'm actually having a really good pregnancy similar to King's," she said to fans back in June in reference to her 3-year-old son, King Cairo Stevenson, whom she shares with ex-fiancé Tyga. "No morning sickness, no cravings—just baby," she declared for the camera.
While both she and Rob have chronicled their lives together as parents-to-be on social media, fans got an even closer look at the stars' personal lives in their own docu-series on E!, which showed the engaged duo preparing for their new life together and their cute addition.
"I fell in love with her immediately because of how great of a mom she is," Kardashian wrote on Instagram in dedication to Chyna on Mother's Day. "Now I'm looking forward to starting a family with her!"
Congratulations to the happy parents! Now, let the wedding planning begin!
