Kendra Wilkinson recently got candid (real candid) about Hugh Hefner’s replacement twin girlfriends an E! camera at the Mansion’s Halloween party.

Says the former girlfriend: “There will only be original Girls Next Door. We built this show. We worked our butts off to be here. Now these girls are coming in afterwards. We’ve made this for them, and I’d appreciate it if they’d be a little bit more thankful… I don’t feel like they’re thankful.”

Shortly after Kendra’s confession, Hef introduces his new girlfriends (including Karissa and Kristina Shannon) and nonchalantly chats about the easy the transition from old girlfriends to new girlfriends.

Something doesn’t add up!
