Ashlee Simpson Files For Divorce From Pete Wentz

In papers filed Wednesday, Simpson also seeks joint custody of son Bronx Mowgli.

On Tuesday, Ashlee Simpson filed for divorce in the Los Angeles Superior Court, ending her marriage of nearly three years to Pete Wentz .

“After careful consideration, we have made the difficult decision to file for divorce,” reads a joint statement from Simpson and Wentz, sent to MTV News. “We remain friends and deeply committed and loving parents to our son, Bronx, whose happiness and well-being remains our number one priority. We ask that everyone honor our privacy as we navigate this next phase of our lives.”

According to documents obtained by TMZ, Simpson cites “irreconcilable differences” as the reason for the split, and is asking for joint legal custody — and primary physical custody — of their 2-year-old son, Bronx Mowgli .

She also asks the court to restore her name to Ashlee Nicole Simpson. In 2008 — less than a month after marrying Wentz — she announced plans to formally change her name to Ashlee Simpson-Wentz .

According to TMZ, the couple did not sign a prenuptial agreement before marrying.

The couple began dating in late 2006 and wed on May 17, 2008, in a non-denominational, “Alice in Wonderland”-themed ceremony held at the Simpsons’ home in Encino, California. The event was presided over by Simpson’s father, Joe, with sister Jessica serving as bridesmaid.

In the months leading up to the wedding, rumors began circulating that Simpson and Wentz were expecting their first child together. Wentz originally dismissed those rumors as part of a “witch hunt” but later recanted, saying that he was just trying to protect Simpson’s right to privacy . Bronx Mowgli was born in November 2008.

In 2009, amid reports that their marriage was in trouble, Wentz e-mailed MTV News to say, “You shouldn’t believe everything you read on the Internet. It’s nonsense.”

MTV News’ e-mails to reps for Simpson and Wentz were not responded to by press time.
