Aguilera sang a portion of the song , alongside " Bionic " and " Not Myself Tonight " , at the 2010 MTV Movie Awards . During " Woohoo " , the last of the set , Aguilera and her backup dancers removed their leather capes and revealing painted red hearts on their groins , ending with Aguilera 's LED heart glowing . James Montgomery of MTV News referred to the song as a " seriously sexy dance number . " Montgomery described the performance 's ending , stating , " Not to be outdone , Aguilera ended things by standing tall at center stage , the camera zooming in on her midsection , which now bore a beating heart of its own . " Most critics were not impressed with the medley , comparing it to Aguilera 's identity during the '' Bionic '' era . Tamar Anitai , also of '' MTV Buzzworthy '' summarized the performance saying it " was all about her " I-I 'm - still-a-diva " vocals , frenzied stage show , and adult-only innuendo ... And then this happened . " She went on to comment also sarcastically , " This is so just Christina Aguilera 's way of saying she loves you ! And that the diminutive diva still has a sense of humor .... 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 . " The song was later included in the setlist for Aguilera 's Vegas residency The Xperience
