It turned into a dance party up in the 'Weekly Idol' studio with Red Velvet as the guests!

All pretense of upholding the girl group image flew out the window as Red Velvet danced wildly to both boy group and girl group songs including EXO's "Monster,"Girls' Generation's "Lion Heart," BTS's "I Need U," TWICE's "Cheer Up," Big Bang's "Bang Bang Bang," IOI's "Pick Me," SHINee's "View," and GD x Taeyang's "Good Boy."

Seulgi, of course, knew the dance moves to all the songs, being the dancing machine that she is. She was joined by Heechul, who probably danced the most vigorously out of everyone. Watch above for a good time with Red Velvet + Heechul!
