AceShowbiz - Amanda Seyfried is adamant a "Mamma Mia!"sequel will never make it to the big screen because script writers have nowhere to take the story. The ABBA stage show became a box office phenomenon when it was transformed into a 2008 film, overtaking "Grease" as the world's top-earning movie musical after pulling in a mammoth $600 million in global ticket sales.

Following the film's success, Seyfried admitted she spread rumor of a sequel around Hollywood because she was desperate to return to her role as lovestruck Sophie. But now the actress has conceded she will never play the part again - as film bosses would struggle to put together a new installment.

She tells Britain's Marie Claire magazine, "F**k no! That's never gonna happen. Like, what would they do? What would they write about? How would they get all the actors back?"
