2NE1's Dara left fans smiling with her belated support for younger brother MBLAQ's Thunder's performance during the '2012 SBS Gayo Daejun'.

Dara tweeted on the 30th, "Yesterday for the 'SBS Gayo Daejun', I worked hard to make an electric sign for the first time. With a trembling heart I waited for Thunder's stage and supported him well but ??…a…a different page was up…this is the first time I've had such a mental breakdown?? so upset, so upset…it was originally this…", along with a photo.

The photo shows Dara looking down in disappointment as she holds up her electric sign which reads, "Thunder!!!".
