Ready to be a big brother! Blac Chyna shared the cutest Instagram video of her 3-year-old son, King Cairo, caressing her growing baby bump on Thursday, June 30.

In the clip, the 28-year-old model, who is expecting her first child with fiancé Rob Kardashian, lifts her shirt to reveal her bare belly and shows her son how to touch her tummy. (We also get a glimpse of her stunning engagement ring.) The smiling toddler follows his mom’s lead and rubs her bump.

“Aww,” she says in the video of the sweet moment.

Chyna shares King with ex-fiancé Tyga, who has been dating Rob’s sister Kylie Jenner on and off for more than a year. While the awkward connection initially caused tension among the Kardashian-Jenner family, most of them seem to be warming up to Rob’s relationship.

Rob, 29, brought his bride-to-be to his sister Khloé Kardashian’s 32nd birthday party at Dave & Buster’s video arcade in Los Angeles on Monday, June 27. Chyna played air hockey with Kim Kardashian, took Snapchats with Kris Jenner and hit the photo booth with the birthday girl for some silly pics.

The Lashed Bar owner and the Arthur George sock designer are currently filming an E! reality series, Rob & Chyna, about preparing for the baby and wedding planning. The couple “will get married before the baby is born in October,” a source previously told Us Weekly.

Rob has been getting good practice at parenting by hanging out with King. He’s been spotted on several outings with his fiancée and her tot. Back in April, the trio went on a tour of a fire station, and Chyna documented their whole adventure on social media.
