After a week of teasing, Christina Aguilera leaked her first single off of her Bionic album, “Not Myself Tonight”. Now she’s up to her old tricks again, taunting us with pics from the track’s music video.

As a general rule, Christina’s videos keep gettin’ better, so we’re excited to see what she’ll do with all those look-alikes. Click to see the Bionic woman prep her first clip after the jump.
