1 Nov - First it was By2 Yumi, then it was reported that he was set to marry Peter Lim's daughter Kimmy.
But it seems that now casino tycoon Stanley Ho's son Mario has found somebody new, a singer named Coco Yuen from the newly established girl group, Girls' Sample.
Romance rumours sparked after Mario shared a photo with Coco on Instagram on Halloween, of him dressed as Jared Leto's Joker and Coco as Harley Quinn from "Suicide Squad", and wrote, "I'm her Puddin'".
Sources also claimed to have seen the two of them holding hands in Ocean Park.
When asked about it recently, Coco admitted that the two of them are dating, although added that it is still in the early stage.
