MotoGP driver Miguel Oliveira is engaged to his step-sister, Andreia Pimenta.
Pimenta is the daughter of Oliveira's father's second wife.
The pair have known each other since they were 13 and have had a secret relationship together for 11 years.
Now, Oliveira has announced their engagement.
Oliveira told Manuel Luis Goucha:
“Before love there was a great friendship. We grew up together. At some point we realized that it was more than a friendship, it is a very strong love. We were going to get married this year, but that weekend I had a race and we had to postpone it next year.”
