The three "Inki Gayo" MC's Nicole, IU, and Koo Hara transformed into K-Pop Doctors during the February 5^th episode of the music program. The three singers, donning white lab coats, acted as scientists delving into the research of K-Pop's success.

In addition to lab coats, Nicole wore a headband with a big red and white bow, IU pinned two blue bows with polka dots to her chest, and Koo Hara sported a headband with a black sparkly bow. These accessories added an adorable touch to the girls' 'lab-look' leaving male fans doting over their cuteness.

This week's "Inki Gayo" featured MBLAQ, T-ara, Se7en, FT Island, J-Cera, NS Yoonji, Rainbow Pixie, Sunny Hill, Teen Top, ChAOS, Dalshabet, Nine Muses, Boyfriend, Brian, B.A.P, DIA, X-5, and Block B.
