Watch Christina Aguilera Perform 'Bionic,' 'Not Myself Tonight' And 'Woohoo' At The 2010 MTV Movie Awards

You THOUGHT that Christina Aguilera's 2010 MTV Movie Awards medley performance of "Bionic," "Not Myself Tonight" and "Woohoo," from her upcoming Bionic album, was all about her "I-I'm-still-a-diva" vocals, frenzied stage show, and adult-only innuendo. And you were right. And then this happened.

SURPRISE! This is so just Christina Aguilera's way of saying she loves you! And that the diminutive diva still has a sense of humor. After all, why else would she STICK A LIGHT-UP HEART RIGHT UP ON HER "WOOHOO"??? It's like a little knowing wink that assures you that when she's not changing diapers and doing mommy stuff, Mamaguilera's hanging out at dance party sex dungeons and wailing from the bottom of her ... light-up hoo-ha. She is DEFINITELY not the same girl who once bopped around on the Disney Channel in a Scrunchie.
