Adam Levine Twitter

Wonder if it will be called Hypocrisy?

When it comes to Adam Levine's new fragrance - coming May 2013! - Christina Aguilera smells something funny ... namely the fact that The Voice coach had mocked the entire concept of celebrity perfumes/colognes about 12 months ago.

"Haha @AdamLevine. What a difference a year makes," Aguilera tweeted along with a link to this tweet that the Maroon 5 singer sent out in March 2011:

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

What a difference, indeed.

The teasing was all in good fun, though, as Aguilera followed up by saying to her NBC co-star, "Welcome to the celebrity fragrance family!"

Levine's scent, 222, will have versions for men and women, BT-Dubs. Phew.

Singer Adam Levine instigated a full scale Twitter war with Fox News after asking that the "evil f-cking channel" no longer play his songs last night.

It's unclear at what point Fox featured his songs and which one(s), but he apparently didn't take kindly to it, firing off this scathing Tweet Wednesday.

And then all social media hell broke loose.

Several of the network's anchors, surprisingly, hit back: "Dear Adam Levine, don't make crappy f-cking music again," Andy Levy wrote. "Thank you."

Redeye host Greg Gutfeld then took aim at the Maroon 5 frontman: "Why did Maroon 5 cross the road?" he asked. "Because crappy music is legal there!"

Gutfeld then retweeted some of Levine's musings and added some sarcastic commentary. Sample tweet, with his response preceding Adam's original:

Names that sound alike: Maroon 5 and crap. @adamlevine Names that sound alike: @kelseygrammer and @chelseahandler.

Levine has never shied away from stirring up controversy on Twitter, but this is taking it to new heights. From an entertainment standpoint, keep it up!
