The stars have not commented publicly on their relationship but the actress accompanied Sudeikis to his native Kansas for the Christmas (11) holidays and they were spotted kissing at a basketball game.

Now, Deadline.com reports they've both signed up for forthcoming film Relaxnious, a comedy about a couple hampered by anxiety and agoraphobia issues.

The movie is also slated to star Fred Armisen and Brie Larson.
