Jessica Simpson reportedly wants to give birth by caesarean section because she is terrified of pain.

The 31-year-old 'Fashion Star' mentor is due to welcome her first child with fiancé Eric Johnson any day now, and has apparently decided last minute she is too scared to push.

The singer-turned-fashion mogul had planned to have a live-in nurse at her Beverly Hills mansion and a luxury birthing suite reserved at Los Angeles' Cedars-Sinai Medical Centre, but after trying and failing to conquer her fears, she is said to have changed her mind about The Method of her daughter's delivery.

A source told In Touch Weekly: ''The thought of going into labour scared the bejeezus out of her. She was so anxious, she was even breaking into cold sweats at night.

''Jessica has no tolerance for pain. She even turned to hypnotherapy to calm her fears about it, but nothing was working.

''She desperately wanted to experience the joy of a natural birth, but decided to go with what made the most sense for her.''

Meanwhile, father-to-be Eric will be on hand to support her through the process.

The source added: ''Eric is a calming force for Jessica. Eric is so excited about the birth.''
