Nick Lachey has been quietly dating stylist Kim Kardashian for about a month, according to People.com. "They're sweet on each other. It's the beginning stages of a relationship," a source told the mag. The two have been spotted getting cosy at a nightclub in Hollywood and were more recently seen leaving an LA theater after seeing The Da Vinci Code. "Part of their attraction to each other is they both have gone through similar life situations," the source added. "They developed a bond. For Nick to settle down again it will take someone who is a lifelong partner." Kardashian, the daughter of O.J. Simpson's lawyer Robert Kardashian, divorced her music producer husband in 2004.
