Jessica says:
“I trained six days a week, two hours a day. I feel confident about my body, although I’m shy.”

As for her 34D breasts, Jessica says: “Mine are definitely real. At school, my boobs were bigger than all my friends and I was afraid to show them. Now, I feel they make my outfits look better. They’re like an accessory.”

The experts do not agree:
NOSE: In 1999 her nose looked broader, now it’s finer - rhinoplasty?

SMILE: She now smiles with none of her upper gums showing - Botox or enlarged using fillers.

EYES: They appear to have changed from oriental to perfect almonds - brow lift.

TEETH: Now a perfect, even smile. Teethwhitened.

CHIN: It used to look longer. Muscles tightened.
