When she commented in a recent interview that she wasn't sure if beau Dominic Cooper is "the one," we thought Amanda Seyfried was just being honest.

Turns out she was being very honest indeed.

Seyfried and Cooper are no longer dating. "Amanda and Dominic have been on and off for a while – and right now they're taking a break," a source says.

"But they're great friends and could still get back together."

While Seyfried has been promoting her new movie Letters to Juliet, Cooper has been at the Cannes Film Festival, where he was spotted talking to - RUN!!!

Amanda Seyfried and Dominic Cooper are done ... for now.

Sorry, we wanted to give Amanda and fans a heads up before saying he was with Seyfried's former Mean Girls co-star Lindsay Lohan, with arms around her.

Moving on with Lindsay? A move worthy of a mean girl ... or guy.

Seyfriend and Cooper met while filming 2008's Mamma Mia! and had a long-distance relationship, keeping close via Skype and meeting when they could.

"There's nothing easy about [it]," Seyfriend tells InStyle.

Apparently nothing at all. But maybe someday soon.
