Report: Pete Wentz Does Not Want DivorceAshlee Simpson-Wentz may be gearing up for a return to her maiden name, having filed for divorce from Pete Wentz yesterday, but the ex-Fall Out Boy rocker is reportedly unhappy about going forward with the split.

Simpson, who married Wentz in 2008 at her parents' California home, began divorce proceedings yesterday at LA County Superior Court. The singer-actress cited "irreconcilable differences" as her reason for wanting out of the marriage and is seeking spousal support from Wentz, with whom she reportedly had no prenup.

According to a TMZ source, Simpson was fed up with her husband's "erratic" behavior and, despite his protests, decided to end things.

The couple announced their news via a spokesperson yesterday, telling fans, "We remain friends and deeply committed and loving parents to our son Bronx, whose happiness and well-being remains our No. 1 priority. We ask that everyone honor our privacy as we navigate this next phase of our lives."
