Listen to Lady Gaga on iHeartRadio

Lady Gaga's Twitter page is up and running again.  The star resurfaced on the social media site over the weekend, unveiling the first promotional image for her upcoming album "ARTPOP." 

Mother Monster poses nude for the photo, seated on a chair made entirely of computer hardware wearing her ever-changing hair long past her waist in a chestnut brown color. 

On Sunday, she made some major announcements about her new single that's making its big debut next month.  Gaga confirmed its title to be "Applause," as previously rumored and also let fans know that "due to public anticipation," she's moving up the pre-order date for the album and its accompanying app.  iTunes will now be offering a pre-order for both on August 19th, the same day "Applause" comes out.
