We covered part I and part II of celebrities and their non-famous siblings and I'm moving on to part III because I am having way too much fun discovering all these siblings!

4Minute's Jiyoon has an older brother who goes by the name of Jeon Jisu. He was introduced to the public on a family variety show called "MBC Bouquet," where MCs Kim Yongman and Jung Hyungdon asked him to rank the members by their looks alone. To everyone's amusement he said, "My sister would be last." He went on to rate Heo Gayoon as #1 in the group for looks.

After School's Jungah and her sister Hyun Soo have the same eyes and all around beauty.

BEAST's resident cutie patootie Yoseob once sang "Happy Birthday" on video for his beautiful older sister Haeyeon. Check it out below:

Epik High's Tablo has an older sister and brother who are just as intelligent as he is. His sister, Lee Sun Joo, graduated from Cornell University and became a lawyer. His older brother, Lee Sun Min, graduated from Columbia University and attempted to debut as an actor in Korea. Mama Lee and Papa Lee must be a proud duo. 

f(x)'s Amber and older sister Jackie are just two old peas in a pod. Back in 2011, the two were spotted doing some shopping at the HuPot store in Seoul, Korea where they posed for loads of selcas together.

Super Junior's handsome member Choi Shi Won, has a little sister named Choi Jiwon. Apparently the two are black belts in Taekwondo, which means any guy who messes with his little sis is going to get a serious butt whopping.

Wonder Girls' Yeeun has an older sister named Go Eun and younger brother named YoSep, making our "Nobody" star the middle child. The last we saw pics of the siblings was when her older sister was getting hitched!
