The Descendants of the Sun actor Song Joong-ki and his co-star Song Hye Kyo's photos-with-baby battle on their Instagram accounts is confusing the fans and making them eager to know the reason behind these posts. After both the actors posted photos with baby girls one week apart, Song Joong-ki again posted another photo with a young boy on Friday on Instagram who almost looks like him.

As expected the photo immediately became viral and more than 200,000 likes in one day. However, like in the previous picture with other kids, the Descendants of the Sun actor did not reveal anything, including the identity of the little boy with him, this time also.

The kid looks so similar to the actor that the fans started speculating him to be the actor's son. Some fans asked him, "Opp. Do you want a son look like him?"

People started speculating the if the little boy is the actor's brother or the child artist who is expected to play his son in the upcoming season of the popular shoe. Some twitter users also joked if the boy is his and Song Hye Kyo's son.

Fans again pressurised the actor to get married and raise a family with his co-actor and rumoured girlfriend Song Hye Kyo. Some fans even commented that Song Joong-ki would be a good daddy and he is a complete "husband material."

It is still not known who is that kid, but in the background of the Song Joong-ki's picture, some people can be seen in a mirror reflection. Thus one thing is proved that he is definitely not the actor's son. From the situation, it looks like the kid is the son of a fan and requested Song Joong-ki to click a picture with him.

Meanwhile, the rumours about the Descendants of the Sun sequel is making rounds and according to the expected plotline Song Joong-ki and Song Hye Kyo will be playing a married couple and will also have kids. So, the kid in the picture can be their child in the upcoming sequel.
