Michael Fassbender and Zoe Kravitz'X-Men: First Class' co-stars Michael Fassbender and Zoe Kravitz were seen getting cozy and reportedly could not keep their hands off each other during a romantic stroll in New York on Sunday.

The rumored couple earlier had brunch with a few friends including actor Ben Foster, who happens to be Kravitz' ex.

UsMagazine.com is reporting that Kravitz, 22, and Fassbender, 34, began dating during the filming of the new 'X-Men' movie in 2010 but the couple did not go public until recently.

A source is quoted saying, "They're really low-key, but they have a great time together just talking music or movies. They really didn't want to be a topic of conversation during the press for X-Men."
