It's a boy for Alessandra Ambrósio! She gave birth to Noah Phoenix on Monday in Florianopolis, Brazil. Alessandra's fiancé and proud daddy, Jamie Mazur, tweeted, "Welcome my son, can't wait to show u around this crazy place."


The couple started dating in 2005 and are already parents to 3½-year-old daughter Anja Louise. They announced their pregnancy in December and the supermodel and Victoria's Secret Angel revealed they were expecting a son in April. Naming their baby boy proved to be the most difficult part. Alessandra, 31, said about choosing a name "[It's} the hardest part! I want something that works well in both Portuguese and English. It can't be too American or my grandmother won't be able to pronounce it!"
