After a week plagued by pregnancy rumors, Kylie Jenner chose instead to focus on boyfriend Tyga's upcoming birthday, throwing an early surprise party for the star, who turns 27 on Saturday, Nov. 19.
The 19-year-old recruited the rapper's four-year-old son King Cairo to help with the intimate bash, and Snapchat videos of the tot greeting his unsuspecting dad are almost too cute for words!
The beauty mogul also baked cupcakes for the special occasion — but next to ones baring King's face, she put others featuring boobs and topless photos.
In one clip, Tyga dips his finger into a dessert decorated with a butt, saying, "Gotta make it more real. Flatten it a little bit." Kylie responded with an insulted "Babe!"
