Kim Kardashian didn’t spend her entire holiday weekend glued to Calvin Klein model Gabriel Aubry. She spent Thanksgiving Day with Aubry in LA, and they saw “Burlesque” there on Friday. But Sunday, the reality star sat courtside at the Nets-Trailblazers game in New Jersey to watch Nets forward Kris Humphries.Friends say Kardashian has known him a while but they could become more than friends. “She’s dating a lot right now,” a pal said. He could fit in with the Kardashians since his name starts with “K” and he has sisters named Krystal and Kaela. Kim’s rep had no comment.
