Adam Levine is learning this the hard way, when his fellow ‘The Voice’ judge Christina Aguilera took it upon herself to call out his hypocrisy concerning his first foray into the celebrity fragrance game with his upcoming men’s and women’s fragrances ‘222.’ Christina Tweeted a link back to a March 2011 Tweet of Adam’s, which read, “I also would like to put an official ban on celebrity fragrances. Punishable by death from this point forward.” “Haha @AdamLevine,” Aguilera wrote in reply. “What a difference a year makes.” She did however, wish him the best of luck with his new venture, writing, “Welcome to the celebrity fragrance family!” Though her comments seemed to be all in good fun, it seems like she really dug deep to embarrass Adam. After all — there’s few things more embarrassing for a band’s reputation than being accused of selling out. Seems to me like there really is a legitimate beef behind these two’s on-screen tension.
