Kim Kardashian fought gravity last night and won!
Wearing no bra and probably some strategically-placed sticky tape, Kim vamped it up for David Letterman last night -- looking sexy in a revealing, sequin-covered black dress.
Kim and Kourtney were on "The Late Show" to promote their new show, "Kim & Kourtney Take New York" -- where Kim said the two "probably gained about 10 pounds eating all the nuts on the street corners" during their time in the city!
