Have you guys noticed that Christina Aguilera and Adam Levine are super chummy this season on The Voice? After their epic Season 2 feud over former Mouseketeer Tony Lucca, we thought they were destined to be foes forever, but it seems like they're finally putting the past behind them and moving on in pursuit of finding pop music's next big thing.

Not so fast, though! There's still some obvious tension between the "We Remain" singer and Maroon 5's tattooed frontman, as seen in this behind-the-scenes clip from week two of the blind auditions.

In the video below, fellow coach Blake Shelton instigates some drama, telling Xtina to stick her fan in Adam's face. Naturally, the feisty diva obliges (though we assume her true motive is showing off her hot new bod). Christina then runs over and proceeds to wave her fan at the rocker, bragging about how she convinced two artists to pick her over Adam.

"Sour graaaapes!" Xtina hums as she saunters back to her big red chair. Burn!

But don't worry, y'all — it's all in good fun. We think. Adam does look a little annoyed as he turns his head away from Xtina and mumbles into the camera something about not even making a pitch, but we're sure he's over it now. After all, he does have some pretty stellar contestants on his team this season, like powerhouse Donna Allen and quirky crooner Nic Hawk.

How do you like them grapes, Christina? Er, apples. You get what we mean.

What do you think of Christina and Adam's chemistry this season on The Voice? Is it the calm before the storm or have they really put the past behind them? Weigh in below!
