Christina Aguilera (Again)
Regrettably, Christina Aguilera didn't learn from the tanning mishap of fellow pop star Miley Cyrus, and she, too, overlooked a part of her body. Christina applied fake tan everywhere except for her armpits.
We understand that most people don't give their armpits much thought, as it's not the most captivating area of the body. However, when applying tanner, it's essential to consider every part, even the less conspicuous ones. Regardless of this tanning oversight, Aguilera still looks stunning!
