Jessica Simpson vs Ashlee Simpson

It seems that Jessica Simpson is jealous at her sister’s success. She is quite unhappy that Ashlee is starting to reach higher fame than her. One source (not disclosed) told Closer:
“Jessica finds it tough being compared with Ashlee, who’s becoming a big star and is threatening to overtake Jessica as the more successful sister. Jessica was always seen as the bigger star, but now Ashlee is taking over. There’s certainly a sibling rivalry between them.”
The fact is that this success is mainly because of Pete Wentz. Ever since she started dating him she has been a regular on the Los Angeles party scene. Paparazzi has been following her like crazy. On the other hand, ever since her divorce to Nick Lachey, Jessica has not enjoyed that much attention. Her movie, “Employee of the Month”, had bad reviews from both critics and fans so she is not that happy. It is strange that sisters in the celebrity world always seem to fight.
