King Cairo will soon have a baby sister — thanks to mom Blac Chyna and Rob Kardashian — but he wants even more siblings, as it was recently reported that he asked Kylie Jenner if she was having a baby with his dad, Tyga!

“[King] said to [Kylie], ‘I know you and daddy are in love like mommy is with Rob, and they’re having a baby.’ So, naturally, King suspects Kylie’s pregnant too,” a source tells Hollywood Life. “It was the cutest thing and Kylie just laughed hysterically and gave him a big hug and kiss.”

Ky, 19, has previously said that she wants to have kids by the time she’s 25 because 30 is “too late” — so little King’s wish may just come true!
