Amanda Seyfried was convinced her boyfriend Dominic Cooper was gay when she first met him.

The pair fell for each other on the set of Mamma Mia! last year and has been stepping out together ever since.

However, Seyfried admits the romance almost didn't happen.

She tells Britain's InStyle magazine, "It was so not instant. I thought he was gay. I didn't know many Englishmen and it was just the way he dressed - he's quite fashionable."
