According to Life & Style, the younger Simpson and her young son Bronx plan to stay with her sibling and fiance Eric Johnson until she finds a place of her own.
A source tells the publication, "Leaving Pete was tough for Ashlee and she needed to be with her family. Jessica told her she and Bronx were welcome to stay with them until she was ready to find a place of her own.
"There have been a lot of family dinners and lots of praying."
Simpson stunned fans and friends when she filed for divorce from Wentz last week. She cited "irreconcilable differences" for the split.
