Model Anna Kay (main picture, left) was recently asked to comment on rumored love rival Christine Kuo.

While Anna Kay enjoys a lavish lifestyle, Christine continues to struggle with her weight, doing everything she can to regain her former figure, reports Jayne Stars and Apple Daily.

Soon after Aaron and Lynn Hung's break up in April, rumours surfaced that Christine had been dating Aaron in secret.

The gossip continued even after both parties denied the claims, putting Christine under extreme stress.

Close sources revealed that Christine was constantly nervous, and worried that the public would think that she was taking advantage of the scandal for publicity.

Christine found comfort in food and her weight ballooned.

The 30-year-old has apparently been taking Chinese medicine and practicing Muay Thai in an effort to lose weight, and has reportedly taken a month off from filming to focus on her weight loss efforts.

Mainland model Anna Kay took over the spotlight when she hinted at her relationship with Aaron Kwok.

She was also seen entering Aaron's home and remaining there for over 30 hours.

When asked to comment on Christine's weight gain, Anna Kay mockingly said, "Is she sick? If so, she should take a break!"

Christine replied, "I'm not sick! I will no longer comment on my health. She added that she will use Anna Kay's comment as motivation, and vows to do her best to slim down before her next public appearance.
