Romero was invited by FINA to compete as a 20-year-old swimmer for the Angolan team in the women's 50 m freestyle at the 2008 Summer Olympics in Beijing. Swimming in heat five, she threw down an Angolan national record time and a lifetime best of 29.06 seconds to round out the field in last place. Romero, however, failed to advance into the semi-finals, as she placed sixty-fifth overall out of ninety-two swimmers in the prelims.
