SHANGHAI, Jan 27 (AFP) - A Chinese woman is so keen to win back her ex-boyfriend that she plans to undergo plastic surgery to transform herself into his favourite actress: Hollywood star Jessica Alba.

The 21-year-old, who identified herself as Xiaoqing, told the Shanghai Daily that she had met with doctors at a plastic surgery clinic in the eastern Chinese city who offered to do the work for free.

"I have made my decision," the newspaper quoted her as saying.

"I'm not only doing it for my ex-boyfriend, but for myself. I am a psychologically weak person. I want to do something to challenge myself and build a strong personality through it."

Liu Qi, an official at the Shanghai Time Plastic Surgery Hospital, said the woman would need eyebrow lifting, eyelid reshaping and nose reconstruction to look like Alba, the star of "Sin City" and "Fantastic Four."

"There's no worry about the expense and it is technically practicable," Liu was quoted as saying. "But the face-lift is irreversible and we hope that she would take it seriously."

Clinic officials confirmed the woman's story, but would not say when or if the surgery would go ahead.

The woman, who works for a web firm, described to the newspaper how her Alba-obsessed 28-year-old ex-boyfriend hung photos of the actress on his walls and stored her image on his mobile phone.

The man demanded Xiaoqing do her make-up as Alba does, even when she slept, and gave her a blonde wig for Christmas, which he asked her to wear all the time.

She told the newspaper they broke up last month when she threw her wig and fake eyelashes to the ground after passers-by laughed at her. But afterwards, she said she reconsidered.

"I love him very much.... That's why I always followed his opinions. I don't want to lose him," the newspaper quoted her as saying.
