Talent seems to run in some families. Actress Park Shin Hye, who starred in "The Heirs" and "Flower Boys Next Door" does not have any siblings who act but she does have a brother who plays guitar and has played in a band.

She recently revealed that her older brother and only sibling Park Shin Won assisted in B1A4's new album.

"My brother did the guitar accompaniment and arranged this song," she tweeted, showing a track list for the group's second full-length album, "Who Am I?" The shot focused on the song "Oh My God."

""It's a good song and his guitar skills have improved," she also tweeted.

BoA is another k-drama actress whose brother has musical talent. Although BoA is best known as a singer, in the last few years she has branched out into acting. She appeared in the films "Make Your Move 3D" and "Big Match" and the drama special "Expecting Romance" with Daniel Choi. She also has a brother who is musically inclined. She might never have been discovered if she had not accompanied her brother to an SM Entertainment talent search. Her brother Kwon Soon Wook produced the dance and drama versions of her music video "Only One."

He also produced the video for Baek A Yeon's song "A Good Boy."

2NE1's Sandara Park and her brother Thunder of the band MBLAQ are both musically gifted but Thunder is the actor in the family. Thunder, whose real name is Cheon Dung, played Yang Kang Woo in "Padam Padam" and nail technician Jin in last year's comedy "Nail Shop Paris."

With so much crossover happening between k-pop and k-drama it's not unusual for singers to also take acting parts but it remains unusual for two singers in the same family to both try acting. That was the case with Jessica and Krystal Jung. Both sisters are talented singers. Jessica is a member of Girls Generation, while Krystal sings in the girl group f(x). Jessica had some drama cameos and a supporting role in the drama "Wild Romance," but this year Krystal made acting headlines when she appeared in the popular drama "The Heirs." She played the adorably possessive girlfriend Lee Bo Na.

Krystal has acted before. She played Ahn Soo Jung in "High Kick 3: The Revenge of the Short-Legged." One day she hopes to do action scenes.

"It's scary to challenge myself but someday, I really want to go for it," said Krystal. "I especially really want to do action scenes where I'm on wires and flying around in the sky."
