It's official, Vanness Wu and Arissa Cheo have split up

Are they still married or are they not?

There's no need for further speculation, as Taiwanese actor-singer Vanness Wu and Singaporean socialite Arissa Cheo have officially gone their separate ways, according to reports.

"My client does not believe in divorce but at this point she is left with no other alternative. She has worked hard for this marriage but given the unhappy state of affairs, she has decided to end it as she no longer wishes to continue to live in hurt and pain," said Cheo's lawyer.

The divorce was finalised after the couple lived separately for three years, Toggle reported. The reasons for their split were irreconcilable differences and that Cheo did not support her husband's career.

Wu, 39, and Cheo, 35, got hitched in a fairytale wedding in November 2013 after dating on-and-off for seven years.

But there were signs of trouble in paradise barely a year into their marriage.

The couple had a public spat over Instagram in late 2014, with Cheo calling her husband a "fake" in a rant. He responded to her outburst with "mind your tongue". They subsequently unfollowed each other on the platform.

After the quarrel, Cheo remained tight-lipped about her marital status while Wu declined to speak about his personal life during public appearances for work.

The couple was hardly spotted together since then - Wu attended fellow F4 member Ken Chu's wedding in 2016 without his wife.

Last September, he denied rumours that his marriage was on the rocks, saying that he was busy filming in China while his wife was occupied with her fashion business.

But rumours of a strained relationship persisted over the years, which was finally found to be true with the confirmation of the divorce this month.

Wu first rose to fame after his role in hit Taiwanese idol drama Meteor Garden in 2001, and recently starred in Cecilia Cheung's comeback drama "Love won't wait".
