When Ambrosio first came to New York, Gisele Bündchen lent her apartment for two weeks and Adriana Lima helped her translate English. She described her typical week as jetsetting from one country to another for photo shoots and in between she has some phone interviews. She still visits her family in Brazil regularly and calls Erechim, Brazil her favorite place in the world and having traveled the world has not yet convinced her otherwise.
In 2005, she broke up with model Marcello Baldrini when she caught him making out with another woman at Marquee. She later dated magazine editor Steve Allain before taking up with Jamie Mazur.
She is very conscious of her figure and works out with her Brazilian trainer doing the Brazilian Butt Lift, which is a mix of samba, capoeira and aerobics. Ambrosio's best friend is fellow Brazilian model Ana Beatriz Barros.
On August 24, 2008, Ambrosio and her fiancé, California businessman Jamie Mazur, had their first child, a daughter named Anja Louise Ambrosio Mazur,in Florianopolis, Brazil.
