Reports say that the 2014 Mnet Asian Music Awards (MAMA) has a mystery singer prepared for the performing line-up.

A CJ E&M rep said to Sports Daily on November 29, “While we’ve released our performing line-up, there is still a singer that has not yet been unveiled. The singer’s identity will no doubt come as a shock to everyone, so stay tuned.”

Just recently, the 2014 MAMA revealed the second half of the performing list, which includes SISTAR, IU, and INFINITE, who joined the previously revealed EXO, G-Dragon, and Taeyang.

The 2014 MAMA will be held on December 3 at 8 p.m. at the AsiaWorld-Expo Arena in Hong Kong.
