Rumours about the pregnancy had been floating around ever since Hannah reduced her public appearances, and was reported to have taken a break from work assignments.
They first met when Quinlivan, then a budding starlet, was working part-time at a fashion store, Phantaci, partly owned by Chou.
Apple Daily reported that the wedding cost approximately NT$23 million (US$1 million).
The couple plans to hold a second wedding banquet in Taiwan around March, and another one in Australia for Hannah’s relatives at a later date.
The couple's parents and about 50 relatives and friends attended, say reports.
