SM Entertainment has uploaded the above picture on their official Facebook pageSMTOWN with the description: "Girls' Generation-TaeTiSeo and Red Velvet at MBC'Show! Music Core'."

In the picture, the two SM girl groups can be seen hanging out at a 'Show! Music Core' waiting room. While Red Velvet appear to be in their casual clothes, posing cutely in the back, established sunbaes TaeTiSeo sit in the front decked out in denim-wear for their performance. Fans are happy to see the different SM generations get along, as they comment on how pretty all the girls look, and wonder if Tiffany and Wendy speak to each other in English. 

In other news, TaeTiSeo has made their comeback on MBC's 'Show! Music Core' with"Holler" and "Whisper". Meanwhile, Red Velvet continues to promote their single"Happiness", which they debuted with last month on August 4.
