Amanda Seyfried is taking a break from Dominic Cooper.

The actress has been dating her Mamma Mia! co-star since the pair met on the set of the movie musical in 2008, but Amanda has reportedly decided to call time on her love affair with the handsome Brit while they figure out where their relationship is going. In an interview last month, Amanda admitted that she wasn’t sure if the 31-year-old hunk was the all too elusive “One.”

“Amanda and Dominic have been on and off for a while – and right now they’re taking a break. But they’re great friends and could still get back together,” a source told

The mag also reported that Dominic was seen spending time with Amanda’s Mean Girls co-star, Lindsay Lohan, during the Cannes Film Festival this week — he was even caught with his arm around LiLo’s waist!
