Pregnant actress Gwyneth Paltrow has been spotted drinking a can of Guinness. The screen beauty, who is expecting her second child, was enjoying an evening out with her Coldplay star husband Chris Martin at New York sushi bar Cube 63. According to onlookers, the Speed of Sound singer pulled a can of the popular alcoholic Irish beverage out his bag after the pair had finished eating, and handed it to Gwyneth who quickly gulped it down. The drink is famous for its huge quantities of iron, an important mineral during pregnancy.

However, the Oscar-winning actress, who already has a daughter, Apple, was not happy with the attention her Guinness guzzling attracted. A source told New York Daily News newspaper: "Everyone was looking at them and she seemed a bit embarrassed. She looked like she was trying to melt into the corner."

Maternal alcohol consumption is the leading known cause of mental retardation in the Western world.
