Dominic Cooper & Lindsay Lohan: New Couple?

Amanda Seyfried and Dominic Cooper are on a break.

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

Less than a month ago, Dominic was spotted kissing Amanda in NYC after attending the Tribeca Film Festival together.

But last night, at the Belvedere party in Cannes, France, Dominic and Amanda‘s Mean Girls co-star, Lindsay Lohan, stayed side by side all night while watching Grace Jones perform!

Dominic is in town to support his new film, Tamara Drewe.
