Has Kate Hudson been getting training tips from sports star boyfriend Alex 'A-Rod' Rodriguez? We only ask as the actress was flaunting an impressive pair of pecs when she stepped out in New York yesterday.

The Fool's Gold star looked supremely toned in a white vest, skinny jeans and knee-high boots as she walked along 54th street trying to hide her cigarette behind a large empty lunch box.

The actress was on her way to an acting studio not far from A-Rod's Manhattan home.

Kate sparked engagement rumours this week after being spotted wearing a diamond ring while cheering on her man during a New York Yankees game.

A rep for A-Rod has denied the pair will be heading up the aisle.
