She was promoting a toothpaste and required to brandish her pearly whites.
But Alessandra Ambrosio's other whites took the focus off her perfect teeth as she endorsed Oral B 3D White in her native Brazil on Wednesday.
The 31-year-old Victoria's Secret supermodel paraded her stunning figure in a tiny romper as she posed on stage at the event in Sao Paulo.
Displaying her trademark slim pins, the mother-of-two looked tanned and toned in the attire. The five foot nine and a half stunner boosted her already statuesque height in a pair of spiky Christian Loboutins and wore several necklaces around her neck.
Joined on stage by two other presenters, Alessandra reclined her famous body in a white chair where she answered questions.
Alessandra also posted a picture of herself at the event on her Facebook page, telling her fans in her native Portuguese that "a pretty smile can help you achieve all that you desire."
The brunette beauty has been doing several projects in her home country of late.
Most recently, the Brazilian model posed seductively on the beach for the new edition of Made In Brazil.
