Christina Aguilera wasn't done with her dripping-wet G-string. The 40-year-old superstar singer is back to posting for her 7.4 million Instagram followers, and she's keeping a promise she made. Christina, who has confirmed a new album is in the works, today showed she puts her money where her mouth is, with the "Stripped" songstress posting straight from an unnamed, but very studio-confirmed, venue on Thursday. She even went with edgy leather, and that coat got kept unbuttoned. Check it out below.
