Lovelyz is this week's guest on 'Weekly Idol'!
On the May 9 episode, the girl group, who recently made their comeback with the new album 'The Heal', joined as the guest.
Being on 'Weekly Idol' also means they need to take a shot at the 2x and roller coaster dance. The girls expressed shock at the super speedy version of their latest song "That Day" but managed to pull through.
Watch the girls try the 2x dance and roller coaster dance in the clips!
