In the recent Golden Disk Awards, (G)I-DLE and ITZY made a stage collaboration by performing Diva by Beyoncé.
While in the recent Gaon Chart Music Awards, you can see a lot of interaction between the two groups.
I hope that the two groups will be more close in the future. You can watch the full interaction below.
