Christina Aguilera is liberated and ready to show the world her new music. The 37-year-old singer just dropped the first song and music video off her new album, Liberation, called "Accelerate" featuring Ty Dolla $ign and 2 Chainz. This marks the first album and single that Christina has dropped in six years. Both the song and the video are going hard on sex appeal, with lyrics like "Pick up your speed," "Stamina, fill me up," and a shot of Aguilera slowly dipping her tongue into a glass of milk. Liberation will be released on June 15, so while you wait, enjoy the very sexy video above.
