Descendants of the Sun stars Song Joong Ki and Song Hye Kyo have been linked together ever since they acted in the Korean military drama earlier this year. The duo has neither confirmed nor rejected news of them being romantically involved, and new reports claim that they were holidaying together in Norway during the actor's 31st birthday in September.

It is not immediately clear from where this news generated, but according to an iTechPost report, Song Hye Kyo recently posted on her Instagram a breathtaking scenery, which many believe is the mountains of Norway. Later, Song Hye Kyo posted a picture of a ship mast that she later deleted. But a fan was able to take a screenshot of the said post before it was deleted, and it is being speculated that Song Hye Kyo was hanging out with Song Joong Ki on the sets of Battleship Island, the actor's new movie.

Song Hye Kyo loves to travel when she has some free time, and it's quite possible that she wasn't accompanied by her rumoured boyfriend during these excursions. Song Hye Kyo recently opened up about her love for travelling saying she loves to visit New York and Paris.

"I love to travel so I visit a lot of places," the actress was quoted as sayin g by SCMP. "I recently went to Jeju-do, a beautiful Korean island, with some of the staff members. I also love New York, Paris and Italy, so I tend to travel to a lot of places with friends when I'm not working."
