Adriana Lima announced yesterday via Twitter that she's pregnant with her second child. But don't expect the Victoria Secret model to be too concerned about the child's sex. She tells PEOPLE magazine:

Boy or girl, we'll be excited either way, As long as our baby is healthy, we're happy!

She also says that she's trying to be good when it comes to chocolate cravings. Over the years, she has proven to be one of the most photogenic supermodels in the world. Here are her sexiest photos from the runway!
