Courtesy: twitter.com/ladygaga Calling the fashion police…literally! Lady Gaga gave fans a sneak peek at a scene straight from her new music video for “Telephone,” where a mostly nude Gaga is only covered by police caution tape! “RING RING its coming little monsters,” the songstress wrote on her Twitter with the pic. The video for “Telephone” supposedly picks up right where Gaga left off at the end of the video for “Paparazzi.” And as if the caution tape didn’t give it away, the video will follow Lady Gaga’s trip to jail, and eventual rescue by Beyonce! But for all the little monsters out there- no worries, Lady Gaga isn’t staying in the buff forever. In an interview with U.K. talk show host, Jonathan Ross, set to air March 5, Gaga says, “I would rather die than have my fans not see me in a pair of high heels. I’d never give up my wigs and hats for anything.” The full video for “Telephone” is said to be released on March 8.
