This gives a new meaning to “Not Myself Tonight.”

Hundreds of fans commented that Christina Aguilera looks unrecognizable in her latest TikTok video.

The “Genie in a Bottle” singer posted a three-minute “What’s in My Bag” ad Thursday in which she sat on a couch while wearing an all-black ensemble and a chunky silver necklace.

She appeared to have a full face of glam, complete with a glittery smokey eye and dark red nails.

However, it didn’t take long for her followers to show more interest in her looks than the products in the video, which has amassed more than 1.5 million views.

“no way thats Christina Aguilera,” one fan commented.

“Someone is pretending to be Christina Aguilera ,” someone else wrote.
