F4's Ken Chu & actress Wenwen Han have filed papers to register their marriage.Due to the country issue, Chu being from Taiwan, and Han being from China, the process was not an automatic one. The papers were filed on March 16th.
It's not known how long the two have been in a relationship together, but they've been together at least since the start of 2015.
The couple was seen in Bangkok recently, which seems to imply they were there on their honeymoon.
F4's only member to not be married is so far Jerry Yan.
