Tomorrow is Tyga’s birthday — but Kylie Jenner went ahead and started celebrating yesterday thanks to Tyga’s son, King Cairo.

Kylie shared snaps of the duo planning for the rapper’s 27th birthday — which included multiple cakes, balloons and super awesome moments between King and his step-mom babysitter dad’s girlfriend.
