Christina Aguilera Needles Adam Levine over New Fragrance Line

Last week, Maroon 5's Adam Levine announced that he'd be bringing out a line of men's and women's fragrances called 222.  But it turns out that just a year ago, Adam had nothing but disdain for the idea of celebrity fragrances -- which his fellow Voice coach Christina Aguilera was only too happy to point out via Twitter. Christina somehow dug up a tweet that Adam sent on March 5, 2011, in which he stated, "I also would like to put an official ban on celebrity fragrances. Punishable by death from this point forward."  She retweeted it for all to see, along with the mocking message, "Haha @AdamLevine. What a difference a year makes... Welcome to the celebrity fragrance family!"  Christina has released a string of fragrances both in the U.S. and in Europe since 2004.  The most recent is Secret Potion, which came out last year.
