We don't think we can say enough that Christina Aguilera has come a long way in gaining her svelte frame back, so here it is again: Christina Aguilera looks amazing.

Last night (Sept. 18) she showed off her toned and trim body on 'The Tonight Show With Jay Leno' in a little black dress, and boy was it black and little.

In the interview, Leno shared Aguilera's snaps from her recent Maxim magazine issue, and the pop star turned 'The Voice' coach discussed how she's a control freak everywhere but in the bedroom -- and that she was never afraid to express herself through her sexuality.

Explained Aguilera, "I'm an artist, and expressing myself in a sexual way, no matter how that changes throughout the years, is something that has always come naturally to me. At this point of my life, I'm 32 and I feel sexier than ever because you know what you want."
