Pecker is a key witness in the case against the former US president, who is accused of falsifying business records to cover up hush-money payment
Joseph Yew and his wife Kang Ting, who is from China's Hunan province, went to the Asian giant on January 24 to spend Lunar New Year with her family, according to the BBC report.
Hunan province borders Hubei, the province where the coronavirus originated.
Yew told the BBC that there had been no sense of panic when they were back in Hunan, especially since the area they were visiting was quite rural.
They returned on January 30, with their wedding due to take place on February 2 in Singapore.
But when guests found out the couple had just returned from China, they started to get worried.
"Some of them said they were not coming," he told the BBC, adding: "We told the guests we would video conference in... some of them were shocked... My parents were not (happy about it) at first but they eventually agreed."
Only 110 of 190 guests made it, including Kang's parents as multiple travel restrictions have been put in place amid fears of the virus spreading.
As of Thursday, the coronavirus has killed 563 people in China and has spread to about two dozen countries.
Singapore has reported 28 cases of the infection so far - making it the country with the second highest number of confirmed cases of the virus outside China (28,018) after Japan (45).
