Victoria's Secret model Alessandra Ambrosio gave birth to a baby girl Sunday in Brazil, she tells PEOPLE exclusively.
"To all of our family and friends, we are pleased to announce that our little princess Anja Louise Ambrosio Mazur was born on Sunday Aug 24 at 7:32 p.m.," Ambrosio says in a statement. "She is 6.3 lbs. and absolutely perfect."
The supermodel, 27, and her boyfriend, California businessman Jamie Mazur, have been dating since 2005. This is their first child.
So far, Ambrosio says, motherhood has been a breeze. "She hasn't cried once except for a second when they pulled her out," says Ambrosio, who continued modeling during her pregnancy, and plans to be back at work in time for November's Victoria's Secret Fashion Show. "We have now felt a new kind of love and joy that we never knew existed."
