The model and businesswoman, 28, said she found out about her pregnancy "a couple months ago," as her and her fiancé are now expecting their first child. Chyna also showed off her engagement ring while attending the DailyMail.com Seriously Popular Yacht Party during the Cannes Lions International Festival of Creativity in Cannes, France.
"We are so excited about the new baby, and his family is, my mom is also, even my son," she continued, adding that her boy, King Cairo, 3, can't wait for a sibling.
As for a wedding, Chyna said "next year" will be the planning phase for her and Kardashian, 29.
"He's a big teddy bear, he's caring, he's so sweet and he's supportive of, like, literally everything that I do," she said of her reality star fiancé.
Chyna was most taken aback by her huge ring. "Look at that rock," she gushed. "Rob is amazing!"
A rep for the couple later confirmed the pregnancy to ABC News. The two have been together since earlier this year.
