After wearing goodness knows what on her head yesterday, Lady Gaga left her hotel in Berlin again this afternoon, this time for a quick trip to the Berlin Wall. Because she was visiting a serious national monument, she wore a dress that looked like tiers of Kleenex (just sheer enough to show her nipples and a flesh-toned thong underneath), plus a fluffy blonde wig, white makeup, and white paint on her hands and legs. She also went barefoot, perhaps because she wanted to clamber atop the wall itself — not an easy feat in Armadillo shoes — and wave her hands in the air like a woman possessed. Oh, and last night she wore a mustache to a club. When you’re Lady Gaga, every day is Halloween, and not even in a fun way at all anymore.
