According to Tencent Entertainment News, the news was revealed by Canadian civic blogger, Frances Bula, who said that Robertson is currently dating the 31-year-old Chinese star, despite their 19 years age gap.
Rumour has it that singer-songwriter Wanting Qu is currently dating Vancouver Mayor, Gregor Robertson.
Robertson has been single since his separation from wife Amy last summer, though the mayor is said to have known Wanting since 2012.
The singer-songwriter had also accompanied Robertson in China back in November 2013 as part of Vancouver delegation on a business and cultural visit to four Chinese cities.
Wanting has yet to respond to the rumours.
