Christina Aguilera at first seemed less than enthused to do this set of musical impressions on The Tonight Show last night, but it turns out she was totally under-selling herself because SHE WAS AMAZING.

XTina whips out a Cher, a Britney, and a Shakira like it's no thing, reminding us all that she is rich and famous for a reason. And that '90s tabloid feuds were so much more fun. CHRISTINA VS. BRITNEY 4EVER.
