What would you do if someone dressed like you and wanted to give you a birthday smooch?
Well, if you're Christina Aguilera reacting to Kylie Jenner, you playfully pucker up.
To celebrate Aguilera's 35th birthday, which is Dec. 18, Jenner, 19, revived her Dirrty-era Xtina costume and partied with Aguilera on Saturday. The soiree had plenty of balloons and pink, which complemented Aguilera's hairdo.

Jenner wore a similar chaps outfit for Halloween, and Aguilera gave it her seal of approval.
