The 'beagles' of Red Velvet are in love with a girl group.

And it's their "sunbae unnies" (senior older sisters), Girls' Generation. To the "baby" girl group who just debuted, Girls' Generation is not only like big sisters to them but also role models.

On Thursday, Red Velvet aired their reality show program on Naver V App.

During their car ride, Girls' Generation's current hit song "Lion Heart" came on and the quintet could not hold in their excitement. They sang and danced along saying, "Girls' Generation got first place on 'M! Countdown' so we all danced together. We love you."

The members all blurted out their love for Girls' Generation, saying, "We love you, Girls' Generation" and "We will become like you one day, right?"

Red Velvet released their first official album The Red on Wednesday and is currently actively promoting their title song "Dumb Dumb."
