According to Znews, Chinese outlet QQ reported rumors claiming that Ho and Bai’s child is currently being raised overseas.

Ho, 30, has been married to Ming Xi since 2019. The couple has two children—a son and a daughter.

Despite a lack of concrete evidence, rumors that he fathered a child out of wedlock quickly spread across social media.

Responding to the speculation, Ho issued a statement dismissing the claims, per Singaporean news outlet 8days.

"First, they said I had a child with another woman, which I already denied in 2019—there is no child!" he said. "Then they said I dated both sisters, which left me completely confused. People’s imaginations are running wild. What’s next—dating aliens from the pyramids?"

Ho holds a master’s degree from the Massachusetts Institute of Technology (MIT). He is also the founder of NIP Group, an esports company that was publicly listed on Nasdaq on July 26, 2024, becoming the first esports stock from China, according to the South China Morning Post. On the same day, Nasdaq Vice Chairman Bob McCooey recognized Ho as the youngest founder of a Nasdaq-listed company in Asia.

His mother Angela Leong, 62, was Stanley Ho’s fourth wife. As of Aug. 3, Forbes estimated her net worth at US$2.4 billion, ranking her 37th on Hong Kong’s 50 Richest list.

Ming Xi, 35, born Xi Mengyao, is known for walking the runway for Victoria’s Secret, Givenchy, Michael Kors, Balmain, and Karl Lagerfeld.
