By mocking his last year's comment about celebrity fragrances.

Back in 2011, when
Adam Levine didn't have a signature fragrance in the works, he made the following comment via Twitter:
"I also would like to put an official ban on celebrity fragrances. Punishable by death from this point forward", Levine tweeted.
Well, a year has passed and the
Maroon5 frontman
scored his first fragrance deal. How things have changed!
The first one to welcome Adam in the celebrity fragrance family and remind him of his comment was none other than
Christina Aguilera!

"Haha @AdamLevine. What a difference a year makes...Welcome to the celebrity fragrance family!", The Voice mentor
wrote and made sure she also added Levine's infamous tweet.
Ha!
How do you like the way Aguilera welcomed Levine to the celebrity fragrance industry? Did he deserve to be mocked a little for his past comment? Make sure to follow 6lyrics on Twitter and Facebook!
