According to sources, Ashlee Simpson is claiming that Pete Wentz’s “erratic behavior” is what drove them apart (Ashlee filed for divorce this morning). TMZ reports that she simply couldn’t handle his crazy behavior. “She really wanted out” their source claims.

While Ashlee blames Pete’s behavior, Pete says it’s not true…they simply grew apart. No third parties were involved in the split. According to one connected source, “After Bronx was born Ashlee made a conscious decision to get out of the business, but Pete’s heart was in music so he kept touring and that became a big issue in their relationship.”

Where it could get sticky…they’re both asking a judge for primary physical custody of Bronx. Hopefully it doesn’t go all Halle and Gabriel!

Wow! I totally DID NOT see this one coming!

According to TMZ, Ashlee Simpson has just filed for divorce from husband Pete Wentz! The couple, who have been married since May, 2008. She’s asking for joint custody and primary physical custody of their two-year-old Bronx.

In documents filed in L.A. County Superior Court, Simpson cites “irreconcilable differences” as the reason for the divorce.

Simpson, who is repped by disso-queen Laura Wasser, is also asking for spousal and child support.   Wentz is repped by Stacy Phillips.

Sources tell TMZ there is no prenup.

So sad!!
