Ashlee Simpson and Pete Wentz are expecting a baby girl tentatively due on October 31.
"Ashlee and Pete are on cloud nine," an insider told Star magazine for its latest issue. "The doctor told them they actually conceived the baby just before Valentine's Day while they were on vacation and has given them an initial due date of Oct. 31. When Pete heard he might have his baby on Halloween, he went nuts. For an emo-rocker type like Pete, that would be just too perfect!"
Pete officially announced Ashlee's pregnancy through a post on his website towards the end of May.
