CHINA’S infamous “professional mistress”, 23-year-old Guo Meimei, has been arrested for illegal betting on the World Cup.

The high-profile courtesan was toppled by careless social media chatter which revealed her illicit activities.

The high-profile woman has become notorious on Chinese social media through flaunting her wealth — posting photographs of herself with expensive items such as jewellery, designer bikinis — and a Maserati.

In 2011 she claimed she had been given the items as “gifts” in her role as a senior manager in the Chinese Red Cross. The ensuing scandal revealed she had no links to the Red Cross and that her wealth was the result of being a “mistress” to Beijing’s rich and famous.

Meimei is now being held along with seven others over breaches of China’s strict anti-gambling laws.

The “professional mistress” had used China’s equivalent of Twitter — Weibo — to express her interest in the World Cup, as well as boast of the bets she had placed.

Police reportedly raided her home and moved upon eight other illegal gambling operations within the capital city, Beijing, claiming such operations were being used by crime gangs to launder more than $140 billion each year.
