Kim Lim, the daughter of Singapore billionaire Peter Lim, was given another ring by her rumoured fiance Mario Ho, the son of gambling magnate Stanley Ho, as the couple spent Valentine's Day in Paris.

Ho posted a photo of their hands on Instagram on Monday (Feb 15), showing them wearing new rings. He wrote: "I want to say she's one in a million, but that's statistically idiotic because then there'd be 7000 of her in the world.

"Therefore, what do you do when you find the 'one in 7 billion'? You "tie her down" with an even nicer ring."

Both had posted on their respective Instagram pages photos taken on an open-air terrace in Paris, with the Eiffel Tower in the background.

Photos posted later showed the couple attending the Uefa Champions League football match between Paris Saint-Germain and Chelsea.

Ho had sparked rumours that the two were engaged with an Instagram post on Dec 30 last year. In it, he wrote: "Beyonce told me if I like something, I should put a ring on it. Well, I liked it so I put my ring on it ?? welcome to Macau, princess Kimmy."
