Christina Aguilera's new album "Your Body"

Christina Aguilera has never looked better!

On September 12, the 31-year-old singer unveiled the cover art for her new single, "Your Body," via Twitter. The sensual shot features a nearly nude Aguilera draped in a sheer pink fabric -- highlighting her every curve. "Can't wait for you all to hear it," Aguilera wrote in the photo caption. The single will be released to radio September 14 and will be available for purchase on iTunes September 17.

"Be sure to watch The Voice on Monday to see a special clip of the music video!" Aguilera also tweeted.

Aguilera's as-yet-untitled new album -- her seventh with RCA -- will be released in November. The disc's debut single is "so good, I hate her for it!" Aguilera's fellow Voice mentor Adam Levine, 33, recently told Us Weekly.

And Aguilera, who hasn't released a full-length album since 2010's Bionic, is eager to share her new music with fans.

"If you love [my 2002 hit song] 'Fighter,' you're going to love my new album," she tells the October issue Lucky. "As a 31-year-old woman, I've been uncovering my independence, and it's been really fun to explore in the new songs."
