Christina Aguilera and A Great Big World performed their hit collaboration "Say Something" at the 2013 AMAs Sunday, live from L.A.'s Nokia Theatre.
With her hair in a braid and wearing a muted black dress, Xtina offered a fairly stripped-down performance compared to the night's more gaudy showcases.
Watch her do her thing along with the group below ...
Following A Great Big World's performance with Aguilera on The Voice, last week, "Say Something" debuted at No. 1 on Billboard's Digital Songs chart.
The band's debut full-length album Is There Anybody Out There? will be released in January 2014 and has fans already waiting anxiously in anticipation.
