King Cairo has got a heart of gold!
Blac Chyna took to Instagram on Thursday to share a sweet video of her and her 3-year-old son cuddling together and gently rubbing her growing baby bump. She captioned the post with a simple, "Aww" and crown emoji.

Cairo is Chyna's son with her ex, Tyga -- Kylie Jenner's on-again, off-again boyfriend. The 28-year-old model announced her engagement with Rob Kardashian back in April. One month later, the happy couple took to social media to share the baby news.
In recent months, King Cairo's lovable personality and adorable fashion style has been featured in his parents' social media posts.

It doesn't get much cuter than that!
