Valdemira Rodrigues de Oliveira said yes to 66-year-old Aparecido Dias Jacob in a ceremony last Saturday
The pair of smitten seniors, with the combined age of 172 years, still held the special engagement despite doctors banning their marriage.
Medics had assessed their health and age and warned the duo, known as Valda and Jaco, would not be able to cope with living on their own.
But after three years together, the senior romantics, who have separate rooms at Nossa Senhora Fatima retirement home in Pirassununga, south east Brazil, were determined to prove it's never too late to be with your soulmate.
The elderly sweethearts exchanged engagement rings in a betrothal service organised by volunteers under an initiative called the 'Project of Dreams'.
Volunteer Fabiane Zaffalon, said: "As they couldn't get married we came up with another way to make their dreams come true by holding an engagement ceremony at the retirement home."
The event was lavishly decorated with a four-tier cake, flowers, cupid ornaments and scattered rose petals.
