Amanda Seyfried and Dominic Cooper are “taking a break” from their relationship.

The actress - who has been dating her ‘Mamma Mia!’ co-star since they first started working together on the movie in 2008 - has reportedly decided to have some time apart from her British lover while they both work out what they want.

A source told People.com: “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.”

Despite months of speculation about the stability of their romance, the 24-year-old beauty and the ‘An Education’ actor are still in constant contact as they try and work through their problems.

Another source said : “They still talk all the time and are trying to work things out. There is no drama. They are just on a break.”

Last month, the pretty blonde admitted she wasn’t sure if the 31-year-old hunk was ‘The One’.

She said: “I don’t know if Dominic’s ‘The One’, but he’s the funniest person I’ve met - and that’s major in my book.”

On Tuesday evening (18.05.10) Dominic was spotted with his arm around Lindsay Lohan’s waist at a Belvedere party at French nightspot LeBaron in Cannes, where they allegedly partied until 5am.

A fellow partygoer said: “It definitely looked like something was going on between them.”
