Whoa! Did we go back in time and not realize it??
Something surely happened because Christina Aguilera is aging backwards!
We can't really think of any other explanation for Christina's major time warp transformation she showed off while promoting The Voice for NBC.
Or maybe girlfriend is just feeling nostalgic for her former self because she is looking sooo 2000 with her fit physique, brightly colored, girly Alaia dress, and that long, wavy mane of blonde hair.
We've gotta admit, we love all of Christina's transformations because she's always keeping us on our toes, but this one is feeling especially sweet.
In fact, we might go put on our best belly top and get our genie on right now!
Ch-ch-check out some more fab pics (below)!
