BIG BANG may be taking a temporary break while T.O.P is serving his mandatory military enlistment but this doesn't mean that other members are idling away. In fact, G-Dragon, Taeyang, Daesung and Seungri are all busy working on their solo materials.

Daesung has recently released the MV for the first track of Japanese mini album "D-Day" to great success. Taeyang is also reportedly busy preparing for his solo album, according to Kpopstarz.

In a recent post by G-Dragon on his Instagram, he is seen lying flat on his back in front of a huge window to what appears to be an old apartment. In his caption, he wrote: "Guess what", challenging his 13 million IG followers and fans to share their theories on what he's been up to. Here are their top 3 guesses:

Magazine Shoot. Most of G-Dragon's fans think that the global fashion icon and BIG BANG leader may be featured in a magazine and that the apartment is the set for the shoot. The presence of a man with his back to his camera hints that GD is not alone and he may be surrounded with members of the production staff.

MV Filming. Some of his fans also believe that G-Dragon is shooting for his solo MV after it was confirmed by sources at YG Entertainment that he will be coming out with a solo album in the first half of the year. GD has also teased his fans with snippets of him working in a studio so they are already anticipating the new material to come out shortly.

Peace Minus One. Could the photo have anything to do with G-Dragon's fashion line Peace Minus One? The set may seem old and dilapidated but GD can make even the grungiest of sets look high fashion because of his unique sense of style. Plus, Peace Minus One is a combination of high fashion and street style so it could be the perfect set to shoot some stuff for the brand.
