Pucker up! Kylie Jenner had some fun with her niece, North West, and Nori’s bestie, Ryan, on Sunday. After the two little cuties attended a birthday party for Tyga and Blac Chyna’s son, King Cairo, they had some makeover fun courtesy of Aunt Kylie’s famous Lip Kits.

“They’re putting on my Lip Kits,” Kylie narrated in one Snapchat video.

She then knelt down to apply her darkest shade to Kim Kardashian’s daughter’s lips.

“You wanted black, right?” she asked as North nodded. “Aww, your little lips!”

When little Northie finally got the black lips she’s always dreamed of, she blew several kisses to the camera.

“Do you like it?” Kylie asked.

“Yahhhhh!” North declared.

Kylie also posted a pic of the two made-up tots, writing, “What happens at auntie Kylie’s stays at auntie Kylie’s.”

Noticeably absent from the weekend’s festivities was North’s famous mom, Kim Kardashian. The reality star has been basically off the grid since her traumatic Paris robbery two weeks ago.

She was spotted out at dinner with a friend last Thursday, keeping a very low profile in a hoodie and flat sneakers.

The mother of two has not made a public appearance since the incident, and apart from unfollowing a few people, has not returned to social media.

"Right now, she's still focused on trying to feel better about the whole situation," a source recently told ET. "Kim is at home with [her kids] North and Saint in Los Angeles. Her mom [Kris Jenner] and sisters visit her regularly. They're being great and supporting her in every way they can."

Thankfully, Kim’s two children, North and Saint, were in NYC with their father, Kanye West, at the time of Kim’s attack.
