Adam Levine and Christina Aguilera Fragrance Feud

Here at "In a Bottle," we love when fragrance and celebrity mingle, especially when there's a whiff of controversy in the mix.

So we were intrigued when we caught wind of Maroon 5 singer Adam Levine's fragrance feud with Christina Aguilera, his co-judge on The Voice. Just as Levine announced he's working on his first celebrity fragrance, Aguilera re-Tweeted a lost post from Levine that bashed star scents.

In his Tweet, Levine wrote "I also would like to put an official ban on celebrity fragrances. Punishable by death from this point forward."

Yesterday, Levine explained to People.com there is a "stigma" associated with celebrity fragrances and he hates them, "100 percent." And his explanation for why he is entering the fragrance fray might irk some other celebs, as he implied their scents are substandard. "I want to do a thing that's never done properly," he told People. "That's my goal."

Levine's fragrance, with a version for men and women, will be called 222, the singer's lucky number.

And Aguilera isn't holding a grudge. "Welcome to the celebrity fragrance family," Tweeted XTina, who is promoting her newest fragrances, Christina Aguilera By Day and By Night, available at Kohl's.
