Looks like Lady Gaga is looking for a fancy zip code. She is the latest celeb to check out the duplex penthouse at 304 Spring Street in Hudson Square (located near that controversial trash tower). According to the NY Post, the Lady checked out the $21,000-a-month penthouse recently—wearing a garter belt, wig, high heels and knee-high stockings, of course. The condo features a private roof deck where the superstar can escape the paparazzi, and a whole lot more. The paper reports she's also looking for a Hamptons beach house. Looks like Yonkers didn't make the cut.
