Couple vow to remain friends
The couple started dating after starring in Mamma Mia! together in 2008.
‘Amanda and Dominic have been on and off for a while – and right now they’re taking a break,’ a source tells People.
‘But they’re great friends and could still get back together.’
A rep for Amanda, 24, was unavailable for comment.
The American actress and UK-based Dominic, 31, had been maintaining a long-distance relationship.
