How you show mutual respect

Trouble behind the scenes at The Voice?. No no no, reassures ContactMusic:

Christina Aguilera has put to rest rumours of a feud with Adam Levine by recording a track with his band Maroon 5.

The stars, both currently serving as judges on hit U.S. talent show The Voice, have ended speculation they don't get along by collaborating on new song Moves Like Jagger.

Oh, yes. It's scientifically impossible for two people who hate each other to appear on the same record. It has never, ever happened in the history of recorded sound.
