Could this be a sign of things to come?
In the latest episode of Keeping Up with the Kardashians, Rob Kardashian joked about having a son named Robert the Third, during a scene filmed months before news broke that the 29-year-old reality star is to become a father.
"What’s your son’s name Rob? I forgot," mom Kris Jenner quizzed Rob, after he made a crack about having a little boy.
"Robert," replied the reality star.
Sister Kourtney then quipped, "I thought it was Cornelius," to which the dad-to-be responded, "His name is Robert the Third, actually."
Rob and his model fiancée, Blac Chyna, 28, revealed their pregnancy news earlier this month.
The baby will be Rob's first child, while Blac has a three-year-old son King Cairo, with her ex, rapper Tyga (aka half-sister Kylie Jenner’s former flame).
King Cairo and Robert the Third – could be quite the regal step-brother combo!
So what do Rob's parents think of the news?
A source close to the star tells ET that Kris “is thrilled about the pregnancy,” while Caitlyn Jenner told us how "proud" he was in the video below.
