The rumor mill is abuzz again about The East costars after a cozy photo of Ellen, 26, and Alexander, 36, popped up on Twitter over the weekend. The picture which shows the two cuddling was in fact tweeted by the movie’s director Zal Batmanglij.
But despite this photo and other pics which show the two suspiciously hanging out together, a source insists to PEOPLE the costars are just friends. Friends who occasionally do the horizontal tango???
