The actress has been spending time in Argentina with boyfriend and baby-daddy Matt Bellamy, whose band, Muse, is touring. Also on the road? Hudson's 7-year-old son, Ryder, from her marriage to Black Crowes frontman Chris Robinson.
The mom-to-be worked up quite a thirst during her stint in the South American country, although her choice of beverage came as a bit of a surprise to onlookers.
The actress was spotted sipping from what looks like a large glass of red wine. While some believe that imbibing in moderation while pregnant is OK, many experts disagree.
The doctor's suggestion? Abstain. "We just don't know enough."
