Its always refreshing to see K-pop idol groups supporting each other. This was exactly what happened when Exo's Chanyeol, Baekhyun and BTS' Suho were spotted on the sidelines of a fashion show doing Twice's "TT" move.

During the event, the three K-pop idols were seen sitting next to each other when TWICE's hit song "TT" came on. At first, the boys started to bob their heads to the tune but when the chorus came out, they could not keep themselves from breaking out the signature "TT" hand gesture.

Chanyeol, in particular, seemed to get into the groove of things as he unabashedly danced along to the tune, with the choreography obviously memorized. When the chorus came, Chanyeol and Suga broke out the shooting fingers together, with Chanyeol playfully pointing at Suho and Suho pretending to be shot. Jin was also spotted doing the move too, reported Koreaboo.

TWICE's songs and dance moves are considered some of the most popular hits to come out of K-pop. Their choreography is so infectious that even top celebrities are doing it.

A recent report by Kpopstarz hinted that singer-songwriter Shawn Mendes, who is responsible for hits like "Mercy" could also a Twice fanboy. Fans have observed that the young artist was seen breaking out the signature "TT" move in several events leading fans to believe that he may be a lowkey K-pop fanboy.

TWICE's "TT" is so popular, in fact that even though it was released last year, its MV is still getting a ton of views on youtube. The "TT" MV recently reached a milestone 150 million views on the streaming site in a span of only four months and two weeks, one of the shortest times to reach the number.

TWICE's "Knock Knock" is also doing well on both the local and international charts. Aside from breaking records for reaching 30 million views in the fastest time. 'Knock Knock" at one point, also reached #1 rank in the iTunes US charts.
