Kim and Kourtney Kardashian’s Sexy ‘Letterman’ Appearance (PHOTOS)

Kim and Kourtney Kardashian’s new reality series, Kourtney & Kim Take New York, premieres on January 23, which can only mean one thing—we’ll thankfully be seeing more and more of them as their publicity campaign for the show kicks into high gear.

The reality TV siblings turned up at the Ed Sullivan Theater in New York on Tuesday to tape an appearance on Late Show With David Letterman and promote the new show, which chronicles the excitement and drama as they open a new Dash boutique in the Big Apple. As usual, the pair looked stunning—particularly Kim, who flaunted her figure in a cleavage-showcasing dress.
