According to the Daily Mail, Harington is trying to win his GoT co-star's heart. "Emilia is definitely interested but is worried their filming schedules would prevent the relationship from working," states the report.

However, Harington might have to deal with some competition. As per the report, Clarke is also being pursued by Cory Michael Smith, her co-star from her Broadway run in Breakfast at Tiffany's. The two actors were seen together at the Vanity Fair Oscars party in March.

"She's very comfortable with Cory but is completely enamoured by Kit. You can see that those two are on a collision course with romance," a source told the Daily Mail.

Clarke's earlier relationship with actor Seth MacFarlane failed due to their busy schedules. The couple split after a few months of dating in 2013.

Harington films his role of Jon Snow in Iceland and Ireland, while Clarke films mostly in Morocco and Croatia, the source told the Daily Mail. Clearly, distance will become an issue if the two decide to start dating.

"It's understandable that Kit would be interested in Emilia — she was voted the most desirable woman in the world by," states the Hollywood Life report.
