Amber Rose was the first person to find out about Blac Chyna's pregnancy.
Blac Chyna
The 28-year-old model - who is expecting her first child with fiancé Rob Kardashian - is "ecstatic" about starting a family, according to the 32-year-old star.
She told PEOPLE magazine: "I was the first person to know, obviously besides Rob [Kardashian]. I wanted to shout it out to the world like this is my baby, but I couldn't. I was screaming and like, 'Oh my God we're having a baby!' Chyna's my family so if she's having a baby, I'm having a baby.
"She's ecstatic. She's pregnant and she's with a man that they're both deeply in love with each other. To be happy and in love and having a baby and getting married. It's a great situation to be in."
Meanwhile, Blac and Rob reportedly already know the sex of their baby but she is struggling with morning sickness.
A source said: "They do know the sex of the baby and will reveal it soon enough. They are so happy about the news. Chyna wanted another baby and said if it happens, it happens. She's not done with having babies.
"Chyna had a bit of morning sickness and felt pretty tired but is doing OK. Rob and Chyna will be getting one of the rooms in his house all ready for the baby. Chyna told [son] King about his new sibling on the way."
And Rob is said to be thrilled about becoming a father for the first time.
A source explained: "Rob was very close to his dad and lost him at a young age. He's never felt like he had a real father figure. He's always wanted to give that to his own kids. He's really a loving guy and will give a lot to his children."
