Poor Kim Kardashian. Everywhere she goes, she’s peppered with questions about still being married to Kris Humphries while pregnant with boyfriend Kanye West’s baby. On last night’s “Late Show with David Letterman,” Dave held nothing back as he pressed Kim on why she isn’t divorced from Kris yet. She explained that the hold up is because Kris is pushing for an annulment, claiming fraud and that she only married him for publicity. Sister Kourtney had the last word on that, quipping, ”I think if she was going to do it for publicity, she’s pick someone that people knew.” Sick burn. Letterman also decided having Kim on the show was the perfect opportunity to revisit Kanye’s infamous “Imma let you finish” upstaging of Taylor Swift at the MTV VMAs, which Kim says is just a reflection of Kanye’s “passion.” Two clips above!
