Pop diva A-mei‘s (張惠妹) expanded waistline has become a hot media topic.

The “culprit” behind her ballooning figure turns out to be the yummy passion fruit-flavored green tea she loves, which possesses a shocking 800 calories per 500ml.

She drinks two to three glasses of the sweet drink, which contains passion fruit, tapioca balls, coconut jelly and TWO BIG SPOONS OF SUGAR, a day to relieve pressure from work,

The 40-year-old has been kept busy with the opening of her new bar with bartender boyfriend Sam.

Reports alleged the songstress neglected the maintenance of her body due to her blissful romance and newfound happiness.

Earlier in September, A-Mei made an appearance on reality singing competition The Voice of China, which incited much talk about her “new image.”
