Kate Hudson was bumpin' big time in Sao Paulo while on tour with her baby daddy, Muse frontman Matt Bellamy.

Wearing a flowy dress that hardly concealed her growing belly, Kate let Matt carry her snakeskin bag -- what a gentleman!

Kate was spotted drinking wine earlier this week in Buenos Aires, which isn't a complete no-no while preggers, but did touch off a storm of controversy. She's going to be returning to the States soon to start promotional duties on her new film, Something Borrowed.
