By2's Yumi Bai seems to have moved on easily from business magnate Stanley Ho's son, Mario Ho, as she was recently spotted hanging out with Elroy Cheo, Taiwanese singer Elva Hsiao's ex-boyfriend.

Meanwhile, there are rumors that Yumi is dating Elroy Cheo, brother of Singaporean heiress Arissa Cheo, after they were recently spotted on a night out together.

On June 6, Yumi shared a group photo on her Instagram page, which showed her sitting beside Elroy. The two were also leaning closely toward each other. Unfortunately, not long after the snap was posted, she took it down, (it can still be seen here).The picture ignited speculations about a romance between the two.

This is not the first time that Yumi is involved in a controversy. In December last year, Hong Kong media was filled with reports of Yumi because she was apparently dumped by Mario after he learned that she had cheated on him.

Yumi was allegedly spotted partying at a club with Chinese celebrity Sun Zujun. Afterward, she called the Ho family's driver to pick both of them up, which angered Mario more.

However, Yumi denies the cheating allegations and insists that the break-up was due to work commitments. Yumi, one-half of the Mandopop duo By2, said, "With regards to those rumors, I wasn't even aware of them at all."

"Readers will believe whatever is written in front of them, but my sister and I know the truth," she added.

In a December 2015 interview, Yumi said that she and her twin sister Miko Bai, the other half of By2, are focused prioritizing their work over romance.
