Taco Belle: Alessandra Ambrosio

Age: 26

Where you've seen her: Since Alessandra Ambrosio is a model, you've seen her in a bunch of advertisements for clothes you would never buy.

Tantalizing tidbit: When Alessandra works out, she does an exercise called the "Brazilian Butt Lift," which sounds hot, but is actually just a mix of samba, capoeira and aerobics. I'm also not sure if she should be doing that now that she's pregnant.
