"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."
Ashlee is seeking joint legal but sole physical custody of Bronx, with visitation rights for Pete. She's also seeking spousal support and is asking to restore her name to Ashlee Simpson.
