Invoking the spirit of ultimate bombshell Jessica Rabbit, and perhaps Madonna-as-Marilyn circa "Material Girl," pop princess Ariana Grande was all va-va-voom and Old Hollywood glamour during her 2015 American Music Awards performance of "Focus."

Taking to the stage in a sweetheart-cut, pink sparkling gown, the tiny singer tossed off her fancy white opera gloves and stripped off her split-leg skirt, crooning against a red velvet draped curtain to a extra-jazzy rendition of her hit Moonlight track.

The show really got started, however, after the curtain lifted to reveal a big white set, full band, and dancers, the tempo of the track kicking up to its typical bold, dancey, trumpet-backed pop version as Ari teetered, shimmied, and clapped her way about the stage in full sass mode.
