Lady Gaga in London London - Arabstoday   Lady Gaga looked pretty in pink while leaving her hotel in London, England. The singer stepped out looking very ladylike in a pretty black skirt and pink top, rather incongruous with fresh speculation that she has undergone a sex change. The 25-year-old pop star was spotted at a studio later in the day wearing a different outfit. Gaga recently treated fans to a sneak peek of her “Marry the Night” video by posting a screen shot on her Twitter page.“It’s Not that I’ve been Dishonest, It’s Just that I Loathe Reality,” she wrote along with a pic of what appears to be her male alter ego, Joe Calderone, lying on a gurney with two nurses by his side. Fans immediately took to forums expressing their excitement at the image.
