London: Hollywood actor Dominic Cooper is reportedly against reconciling with Amanda Seyfried and is back with his Ethiopian-born actress-girlfriend, Ruth Negga.

Cooper, 33, and Seyfried, 25, who met on the sets of `Mamma Mia!` dated for nearly three years before splitting in 2010.

Post the split, Cooper got into a relationship with Ruth, 29. The couple, who reportedly remained aloof for a while, is back together and was spotted dining at the Dean Street Townhouse, Soho, reported Daily Mail.

"They were completely lovey-dovey. They looked like an item and left hand in hand," said a source.

A friend of Seyfried said, "She is devastated to be single once again and will be very upset to hear Dominic is back with Ruth."

The `Devil`s Double` star met Ruth at the London National Theatre in 2009, where the pair played lovers in the Greek tragedy `Phaedra` and it soon spilled over into real life with sources catching them kissing in their dressing rooms.
