And nope, not her barnet - her eyebrows!
The Bad Romance songstress is now famed for her super-edgy, barely there brow look and even sported platinum arches alongside Kendall Jenner on the Marc Jacobs catwalk during New York Fashion Week - but she revealed that the upkeep is absolutely cer-azy.
"I bleach my eyebrows every day," the songstress told US Weekly. "I like to keep them light."
Anyone else totally shocked that they haven't fallen out by now? We also dread to think how many pots of Jolene she gets through a month...
Aside from the fact that bleached brows set her apart from all of the other members of Celebville, Gaga mentioned that she dyes them because she just loves to channel her inner beauty chameleon.
Kylie Jenner, eat your heart out.
"They're more versatile for a beauty look," Lady Gaga told the publication. She continued, "You can draw [over your eyebrows] any way you want when they're bleached."
Well drawing them on is exactly what you'll be doing if you continue, Gaga - eeek!
