The couple shared a tender kiss aboard a luxury speedboat

The couple were seen kissing aboard a speedboat as Justin touched down in Oslo to continue his European tour.

According to The Mirror the SexyBack singer said he was forced to send the actress back to the U.S. recently because he finds it difficult to focus on his work when he is with her.

He told The Mirror: "Jessica met up with me in Manchester, England, but for Paris I told her categorically no. This tour is very important to me. I'm doing it really seriously so there's no question of playing sweethearts."
