We're used to seeing Mario Ho making headlines for all the good things: His thriftiness (he's a fan of Uniqlo underwear), his high-achieving brain (he's an MIT alum and a known math genius), and even how much he dotes on his wife, Chinese supermodel Ming Xi, with whom he has two kids. 

Recently, a wave of explosive allegations against Mario, who is the son of late Casino King Stanley Ho, sent Chinese social media into a state of frenzy.

In a series of defamatory posts on Weibo, the 30-year-old was accused of infidelity, having an illegitimate child, and even being in a incestuous relationship with his sister.

A netizen claimed that Mario has a child with Yumi Bai, one-half of Singaporean pop duo BY2. He reportedly dated Yumi back in 2014.

It was also alleged that Mario was also involved with Miko, Yumi's twin. 

The netizen then claimed that Mario has an ambiguous and messy romantic relationship with... his younger sister, Alice Ho.

Both Alice and Mario are the children of Stanley and his fourth wife, Angela Leong.

Never one to back down from a fight, Mario took to Weibo to rubbish the rumours.

“First they said I had a child with another woman, which I already denied back in 2019 — no child! Then they said I dated both of sisters, which just left me completely confused," he said.

He condemned those fabritcating rumours about him and his sister, adding that he's baffled by claims that he and Alice were 'kidnapped together" and their 'relationship' blossomed then.

"Everyone’s imagination is too wild. What’s next? Dating aliens from the pyramids?," he questioned. 

While he didn’t think these ridiculous rumours warranted a response, he felt he needed to issue a statement for the sake of those involved.

“It’s all fake, fake, fake," he emphasised. “Just because a woman takes a photo with someone doesn’t mean you should jump to conclusions about romance, affairs, or children. Please show some respect.”
