Sometimes you come across sibling pairings where one looks nothing like the other, and you have to ask over and over again, "No seriously, are you guys really related?" To put it less nicely, you sometimes come across siblings where one looks like he or she grabbed two fistfuls from the good gene pool and left nothing for the other sibling #selfish.

Well that doesn't apply for the following sibling pairings because, as it turns out, good genes do run in their families. These siblings of celebrities aren't celebrities themselves, but they'll have us fooled with their good looks. Though they could easily enter the entertainment field based on their appearances, these celebrities' siblings are mostly students or have careers of their own (meaning celebrities' siblings such as Nichkhun's Cherreen, a TV actress, are not included). 

Here are 10 stunning celebrities and their equally stunning non-celebrity siblings. 

Kim Yoo Jung X Kim Bu Geun 

I'm seeing double!  Who knew child actress Kim Yoo Jung was hiding this hottie of a brother? Her older brother (surprisingly, not identical twin), Kim Bu Geun, has been gaining a lot of interest after he posted a selfie of himself with his younger sister in the background. Viewers immediately noticed their striking resemblance, dewy eyes and all. Kim Yoo Jung commented, "I'm not sure since I see him everyday, but people say he's good-looking." 

Kyuhyun X Jo Ara 

Kyuhyun's older sister Jo Ara has been a violinist for close to 20 years and has studied abroad at the prestigious Vienna School of Music in Austria. On KBS 2TV's 'Superman Is Back,' she was revealed to be Haru's violin teacher. She even performed with her younger brother on 'Immortal Song 2.' 

Mir & Go Eun Ah X Bang Hyo Sun

Bang genes must run strong in the family because Mir, his older sister (actress Go Eun Ah), and their oldest sister Bang Hyo Sun look identical. The three siblings share wide-set, charismatic eyes, and cute button noses that make them look way too young for their age. Don't let youthful appearances fool you, though, because Bang Hyo Sun is a married woman with a five-year-old child.  

Roy Kim X Kim Hye Soo

When Roy Kim first appeared on M.net's 'Superstar K4,' viewers expressed keen interest in his sister, Kim Hye Soo, who, along with her mom, came to show her support. Since then, she's been gaining interest for her innocent-looking charms, smooth black hair, and pale skin. Her mother has also garnered much interest for her elegant charm and beauty. Netizens have been commenting that Kim Hye Soo looks like a cross between Jang Yoon Jung and Taeyeon. 

Dara & Thunder X Park Durami

Dara and Thunder are famous for being celebrity siblings who never seem to age. But little do people know that they actually have a third sibling who looks exactly like them. The middle child has been revealed to be Park Durami, who, unlike her famous siblings, is a university student working toward her degree and keeping her life private. She shares a five-year age gap with Dara and one-year age gap with Thunder.

Minho X Choi Min Suk

SHINee's Minho is known for his good looks and unparalleled athleticism, but it seems his older brother might be giving him a run for his money in those two departments. Choi Min Suk has received explosive attention for his sharp features. He's not just a pretty face but also a student at the elite Seoul National University studying Physical Education. 

T.O.P X Choi Hye Yoon

Netizens have likened T.O.P's older sister Choi Hye Yoon to a celebrity for her beauty. With long black hair, round eyes, and a slim jaw line, Choi Hye Yoon has been drawing a lot of attention for looking like a doll. She and T.O.P prove the superiority of their genes. 

Sulli X San

Sulli revealed pictures of her adorable baby brother, San, who's now only four-years-old. In the picture, her brother shares the same doll-like face as his older sister and is full of aegyo. Granted the sizable age difference, Sulli has commented that she's raised him as if he's her child. It's too early to tell now, but give him a couple of years and he'll be making ladies swoon.

Yenny X Park Yo Seb

Yenny revealed her handsome younger brother, Park Yo Seb, via photos on her Twitter from her sister's wedding day. His straight brows and cute features bear a striking resemblance to those of his older sister's. Park Yo Seb plans to become a pastor after he graduates from his theological seminary. He will be following the footsteps of his parents, who are leading a church as well.
