Kylie Jenner is practicing her stepmom duties!
The KUWTK star was having fun on Snapchat when boyfriend Tyga's son King Cairo jumped on her bed and unexpectedly wrapped his arms around the 19-year-old beauty.
Wearing a cute onesie, the four-year-old cuddled with Kylie, who sweetly captioned the snap, "This guy."
Kylie has been including King in her social media lately, posting a mirror selfie with the toddler and even throwing him a Ferrari-themed birthday party last month with the "Rack City" rapper.
And Blac Chyna is fine with lip kit guru spending time with her little boy.
"She could babysit the baby and King at the same time,” Chyna said on Facebook Live, also referring to her newborn daughter.
