A heavily-pregnant Ashlee Simpson-Wentz is so petrified of natural childbirth, she’s already opted for a scheduled C-section.

The 24 year-old songstress is expecting her first daughter with husband Pete Wentz in October, according to reports.

Ashlee has been plagued by nightmares after Lamaze classes freaked her out about natural labor.

“Ashlee planned to go through a natural childbirth, but the classes changed her mind,” says a pal.
