Joining A Great Big World onstage for a performance of Say Something, Christina Aguilera was simply chic and STUNNING in a low-key black gown.
We love her style transformation lately! So elegant and classic!
And her hairdresser deserves some major props for taking the singer’s hair from fluffy curls to sleek crown braid in such a short time.
Excellent all-around!
