Alessandra Ambrosio Jamie Mazur Brentwood Santa Monica

Alessandra Ambrosio's body is absolutely bangin'.

The model showed off her taut tummy while spending some quality time with her fiance Jamie Mazur on Friday. The couple, who are still going strong, despite rumors of a breakup, went shopping in Santa Monica yesterday. They got engaged in 2008 after three years of dating, but haven't set a date yet for the wedding.

Even dressed down in a plain black blouse and ripped, destressed boyfriend jeans, Alessandra looked smokin' hot as her crop top showed off her enviable frame.

It seems impossible that the Victoria's Secret angel has two children: 5-year-old daughter Anja and 17-month-old son Noah. Jamie is one lucky man.
