Christina Aguilera Had Some Thoughts About Kylie Jenner's 'Dirrty' Costume

The pop diva has spoken.

We'd expect Christina Aguilera would be hard to please. She is the fiery pop vixen who once sang, "I'm a genie in a bottle. You better rub me the right way," after all.

So when Kylie Jenner, to much "YASS"-ing, debuted her spot-on XTina costume on Instagram, we waited with bated breath for the "Dirrty" diva to issue a verdict.

This just in: Christina liked the imitation, even re-posting Kylie's costume with a wildly complementary caption: "YAASSSSS.....Killin it @kyliejenner yes to dirrty 2016!! Get it girrrl!!!"

We can all breathe easy.
