Rob and Chyna just confirmed the baby news on Instagram with a pregnant Chyna emoji. Tyga also sent his well wishes, writing "Congratulations" under Chyna's announcement.
The couple, who went public with their relationship in January and recently got engaged, were spotted at an Ob-Gyn’s appointment in March.
Blac Chyna is already the mom of son King Cairo, 3, with ex-fiancé Tyga, who is currently dating Kardashian’s half-sister Kylie Jenner.
The Arthur George sock designer, 29, and former music video model, 27, have been nearly inseparable since first stepping out together. As previously reported by Us, Chyna has helped the formerly reclusive Kardashian drop almost 70 pounds.
Kardashian proposed to his love with a stunning 7-carat engagement ring, and as previously reported by Us, are ready to make it official. "They want to get married toward the end of the summer,” the insider told Us. “Somewhere warm.”
Although Kardashian's famous family was slow to warm up to their romance, Chyna has since repaired her friendship with both Kim Kardashian and Jenner, thanks to the Selifsh author.
