Conan O'Brien may be older than Christina Aguilera, but the singer still has a thing or two she can teach the red-haired TV host! She proved it last night when she visited him on the set of his brand new TBS talk show.

O'Brien got a double dose of Aguilera; after the interview was done, she tore down the house with her own spin on an Etta James classic. Check it out below:
