On Monday evening, Leigh-Anne shared a close-up pic of wearing the ring as she held hands with her footballer fiancé
She captioned the snap; “Heartbroken”.
According to reports, the police are investigating the theft of the bespoke emerald and diamond-encrusted gold band, which Andre bought ahead of his proposal to Leigh-Anne last year.
It is not clear if the thief was known to the couple, or an opportunist intruder.

Earlier this month, the couple revealed they are expecting their first child.
Leigh-Anne shared the news with a pregnancy photo-shoot posted on her Instagram page.
