Mamma Mia star Amanda Seyfried has admitted she wasn’t an Abba fan before landing the lead role in the film.

Amanda, 23, stars in the film adaptation of the hit musical alongside Meryl Streep, Pierce Brosnan and Dominic Cooper, who she is now dating.

She said: “I knew Dancing Queen. But then when we started working I realised there were all these songs that I’d heard but never realised were by ABBA.”

Amanda also talked about her musical performance at this year’s Oscars ceremony alongside a host of other stars.

She said: “As I was filming in Toronto, I had one day to rehearse – Dominic had been in LA all week and still didn’t get it by the time show time came around.

“We were so nervous and we had Vanessa Hudgens and Zac Efron with us, who were rock solid, the perfect students. I almost fell down the steps during the live show – Dominic caught me.

“But hey, I got to hold hands with Hugh Jackman on the Oscars stage, which was pretty ridiculous in itself!”
