Christina Aguilera, Justin Bieber, Beyonce, Mariah Carey, Faith Hill, Jennifer Lopez, Katy Perry, Rihanna, Britney Spears, Taylor Swift and Usher are just some of the singers who have their own fragrances.
"I really don't know if I would do the whole fragrance thing, because I don't want to smell like anybody else," Underwood told AOL.
The 'Good Girl' singer added: "You go to Walgreens and you just see everybody [on the shelves]. So that one's not quite for me.
"If people walked up to me smelling like me, it might weird me out."
Underwood is gearing up for the release of her fourth album Blown Away, which comes out on May 1.
