TaeTiSeo shared behind-the-scenes stories from their "Holler" music video at the showcase for their new album on September 16.
 

Tiffany revealed, "For the 'Twinkle' MV, we changed our outfits 7 times. I wanted to do it bigger and better this time around." Seohyun also said that Tiffany was involved in a lot of the production process. "Tiffany unni was involved a lot this time. It's to the point that you can say that she created it. I'm thankful because the end product came out really pretty and cool."

Taeyeon also made the crowd laugh with a funny bts story. She shared, "There's a scene where we sit on a pink hand. We're actually sitting on bubble wrap because of the spangles on our clothes. Our expressions are so charismatic, but it was all water under there so we had to put all our strength into it. If we didn't use our muscles, we would've dove into the water."

In other news, TaeTiSeo will be making a comeback with "Holler" on this week's 'M! Countdown'.
