Just like every year, a contestant duets with their coach, and Alisan Porter's coach this season is Christina Aguilera. Alisan Porter & Christina Aguilera's studio cover of "You've Got a Friend" was originally done by Carole King, and James Taylor. The song is available on iTunes to purchase.

Love it

This may be her best Voice contestant duet so far. It's tied with The Prayer for now until I decide. <3

This was great, but I prefered her solo-performances
