Alessandra Ambrosio skinny shorts gym

Even if she wasn't wearing a "Don't Worry Be Sexy" tee-shirt, it'd be hard not to notice her!

On Tuesday Alessandra Ambrosio was snapped leaving the gym, and the Brazilian beauty showed off her long and slender stems in a pair of itty bitty black spandex shorts. So how does she stay so skinny?

Just a few weeks after giving birth to her second child in May, Ale began walking and doing yoga, and after 60 days of that, she added in daily Pilates and spinning workouts. While she was pregnant, her diet consisted largely of fresh green juices, kale salads and fish. Hmm, that doesn't sound like a lot of fun! But she does look amazing...
