IU recently showed her support for Loen Entertainment's new girl group, FIESTAR, by making an appearance on the set of the group's new music video.

On August 5th, IU�posted the above photo via her official Twitter page and wrote, "On the set for�FIESTAR's MV shoot. Cheska unni is looking cute today. They are all pretty."

Fans took note of IU's face in the photo, which was only half as big as the 8x11 sheet of paper she was holding up. On the sheet of paper was the autograph of FIESTAR member Cheska, who evoked laughs by posing next to IU holding a marker as if it was a microphone.

Meanwhile 6-member rookie girl group FIESTAR participated in Loen Tree's "Sea of Moonlight" along with IU back in July, which you can check out the�review for�right here on allkpop.
