When we shot these exclusive pictures of Hayden Christensen and Emma Roberts looking pretty cozy on the set of their film Little Italy back in June of this year, we didn’t think much of it.

But now, with the report that Emma was at the center of Hayden and Rachel Bilson’s split… we had to give them a second look.

Us Weekly reports that Bilson found text messages between Christensen and his Little Italy co-star, which led her to believe that they were having an inappropriate relationship.

But neither Hayden, nor Emma, have addressed the rumor.

And we’re only left to speculate.

But they sure look like they were getting along while filming the romantic comedy in Toronto Canada.

Of course, you could say they were just acting.

Or you could remember that where there’s smoke… there’s fire.
