After successfully becoming one of the most successful rookie groups to debut in recent years, EXO is gearing up for a comeback.

Recently it was revealed that EXO has officially wrapped on their comeback music video after three days of filming. Depending on what happens in this video in question, the boys may have had a grueling schedule. Although it is yet to be confirmed what the song is, over the past few days fans have speculated that the title track for their upcoming second studio album is titled "Call Me Daddy."

Back in January when EXO's comeback was first announced, SM Entertainment released the following very vague description of the company's plans for the group's comeback:

"The new album and concept have not been arranged in detail yet... The members are working hard to prepare the album to show a variety of images," said an SM Representative to Star News (via Allkpop).

"Variety of images" seems to work as a description for the rumored title track "Call Me Daddy." The rumor reportedly surfaced after fans spotted EXO in the credits for MSA Agency's creative directors and choreographers Napoleon and Tabitha Dumo's list of credits. The power team is responsible for big star names like Ed Sheeran, Calvin Harris, and TVXQ.

Fans then scoured the internet and found a song entitled "Call Me Daddy" on producer Danja's SoundCloud account that is speculated to be a demo for the song. Somewhat humorously though, a few fans have tentative feelings toward the concept.

Only time will tell if "Call Me Daddy" is ultimately the title track from the upcoming second album by SM Entertainment group EXO. EXO is expected to debut their comeback song and some unreleased tracks at their five-day concert EXO PLANET #2 - The EXO'luXion. The concert will be held at the Olympic Park Stadium in Seoul on March 7, March 8, March 13, and March 15.
