Siblings may bicker, but can also support one another and that is definitely the case with several notable K-Pop idols. The Jeon and Jung Sisters, two sets of idol twins, and the nation's little siblings have proved that even the K-Pop industry has room for family.

The Jung Sisters

Girls' Generation's Jessica and f(x)'s Krystal may be in other groups at SM Entertainment, but the two have worked together on more than one occasion. Not only are the sisters currently filming the reality show 'Cover Girl' together, but they have also been a popular modeling team and have appeared in several photo shoots. Together, Krystal and Jessica have become known as fashion icons.

The sister vocalists have performed together several time at various SMTown concerts, and recently sung a song with EXO's Kris for the Make Your Move soundtrack.

Tasty

The main focus of Tasty is the fact that Daeryong and Soryong are identical twins, so they rarely can avoid the fact that they're siblings. Although they each have solo activities, since their debut the two have promoted together and their K-Pop identity is founded on the basis that they are twins. Even their fanclub name, Twings, is derived from the idea that the fans will be the wings that the twins fly on (or that the fans are Tasty's wings).

Akdong Musician

The sibling duo Akdong Musician has recently shot to the top of numerous music charts, proving that idol siblings can definitely work well together. Lee Chanhyuk creates the sound for the duo, while his sister Lee Soohyun is the main vocalist. They may be young, but they're the most popular siblings in Korea today.

Boyfriend

The second set of twins on this list, Jo Youngmin and Jo Kwangmin may be part of the six-member idol group Boyfriend, but they definitely stand out. Youngmin and Kwangmin were also child actors, so weren't new to the industry when they debuted.

Boyfriend was the first idol group to have twin members, and has taken advantage of the fact that the two are identical. The two starred in the music video for 'Janus,' where Kwangmin and Youngmin portrayed two sides of one person. (Janus was a Roman god with two faces.)

The Jeon Sisters

 Not to be confused with the Jung sisters, T-ara's Boram and D-Unit's Ram (Wooram) are actually the daughters of Jeon Youngrok, a popular singer, and Lee Mi Young, an actress. Their grandparents were also famous singers, making the two third generation singers. They recently were featured in a variety show, Wooram's Family Camp, with their father.

Special shout out to 2NE1's Dara and MBLAQ's Thunder. Even though the two haven't worked on any official projects together, they've showed off their close relationship several times.
