Somers testified that her father bullied her mother to get the face-lift and insisted the plastic surgeon prescribe an unusual combination of painkillers and other drugs for her recovery.
Two days after the surgery, Somers said, she confronted her father after finding her mother knocked out by the powerful drugs.
Somers, also a doctor, recalled her father saying, "'I must have given her too much medicine.'"
Michele MacNeill had tried to delay the surgery until she could reduce her high blood pressure and weight and to wait until her daughter could help take care of her, Somers said.
Somers, who has adopted her mother's maiden name, described an argument between her parents about the timing of the surgery.
"He got angry at my mom and said, 'If you don't have the surgery now, you're not getting it,'" Somers testified.
