41-year-old A-Mei and her 35-year-old bartender boyfriend, Sam Yao, is said to be in a relationship for three years now.
According to an article in Asian Pop News, since dating the Taiwanese singer, Sam has seen a transformation in his life.
He is reportedly living in a NT$300 million luxurious property and is driving a NT$5 million Porsche car, all said to be provided by A-Mei.
Two years ago, A-Mai also invested NT$15 million in a third night club for him to oversee the business.
However, just last month, tabloids reported that Sam was seen hurling profanities at A-Mei publicly at the night club.
In a drunken state, Sam's emotions ran uncontrollable and he screamed at A-Meu, "A-Mei, who do you think you are!"
After this report, A-Mei's fans lashed out at Sam and even urged her to break up with him.
Recently, however, eyewitnesses shared that there are some discrepancies in the reports.
They said that Sam was instead pressured by friends to consume champagne and various mixed drinks. After he was heavily intoxicated with alcohol, Sam started to have a spat with the bartender.
As A-Mei was extremely tired because of her hectic schedule and seeing that her boyfriend had lost control, she left the place first without informing him. Sam then flared up after realising she was not around.
He shouted: "Where is A-Mei? Why is she missing?"
After the incident, he had reportedly apologised to A-Mei and said: "It was so embarassing. I was badly drunk yesterday."
