Fergie's actor husband doesn't listen to her music when he's filming.

Josh Duhamel - who married the Black Eyed Peas singer in January - has admitted while his latest film 'Transformers: Revenge Of The Fallen' has a rock soundtrack featuring Green Day and Linkin Park, he prefers 1970s pop.

Josh said: "Really, I mostly listened to ABBA on the set."

He also talked about preparing for his physically punishing role as Major Lennox of the US military in the movie.

He added: "The director, Michael Bay, told me: 'Be in shape. I demand a lot from my male actors, especially in these movies.'

"I tried to be as strong and ready to go as possible. I was so glad on those days when I was running non-stop in the sweltering heat.

"The gym doesn't begin to prepare you for that one."

US actor Josh also felt a duty to portray his role as realistically as possible in honour of his friends who are currently fighting for their country around the world.

He added:"We took a lot of pride in trying to represent the military as closely as we could. I've got a lot of friends in the army and an aunt over in Iraq, so that was my main focus was to try to represent them all and make them proud."
