Alessandra Ambrosio Wears a Sports Bra | Pictures

Alessandra Ambrosio wore a sports bra and short shorts for a yoga class in LA yesterday. Her fiancé, Jamie Mazur, brought their young son along to drop her off for the session. Later in the day, she was solo and covered up in a white top to run errands.

Alessandra hung out at home over the weekend, and tweeted about the unusually hot temperatures in LA. On Saturday, she tweeted about enjoying a pool day since it was "so hot in the west coast!" She was also at the beach Sunday, trying to cool off in the Pacific. Alessandra and Jamie had a big start to the Summer with the birth of their second child, Noah, in May. The excitement will continue over the next few months, with the annual Victoria's Secret Fashion Show around the corner. The spectacle doesn't air on CBS until December, but Alessandra's already gearing up to hit the runway. On Sunday night she posted an ad for the VS program with the caption, "it's almost show time!"
