Pete Wentz is busy learning to sew for the pending arrival of his baby girl.

The FNMTV host and wife Ashlee Simpson-Wentz will welcome a daughter this October, according to a new scoop from Star Magazine.

“Ashlee and Pete are on cloud nine,” an insider spills. “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!”
