Kim Kardashian and her sisters, Kourtney and Khloe, appeared on David Letterman Tuesday to push their new line of products at Sears.  But Kim also raised doubts about whether her new husband will be returning to the Nets.

When Letterman asked if Kris Humphries played for the Nets, she responded, "He plays for the Nets" then paused and added, "He did last year." A bit later, she offered without being asked, "I don't know where Kris is going to play next year." When Letterman asked where she hoped he would play, Kim went all coy. Her sister didn't. Kourtney (not the one married to Lamar Odom) exclaimed, "The Lakers!" While not going near that line, Kim did say, "New York just kills me."
