Chyna's ex-fiance, Tyga, commented on the photo by simply saying "Congratulations" while Rob's sister Kim and her husband Kanye West liked the post.

Tyga who shares a child with Chyna is currently dating Rob's youngest sister Kylie Jenner.

A source close to the couple revealed that the duo wanted to announce the pregnancy on Mother's Day but was blindsided when the pregnancy was leaked to the press yesterday.

The source also revealed that "Chyna was very upset about the leak and suspects that a member of Rob's family leaked the news to promote their show 'Keep Up With The Kardashians' in which Rob will be making an appearance." the source also added "Chyna's family is very supportive regarding the pregnancy and her relationship with Rob."

In the premiere episode of the 12th season of Keeping Up With The Kardashians, Kris was seen defending herself about supporting Rob after Kim and Khloe called her out and told her to stop paying his bills.

Chyna is said to be in the first trimester of her pregnancy. In February, she was arrested for alleged public intoxication and drug possession after police found two ecstasy pills in her handbag.
