We were all fairly freaked out when our favorite K-drama couples swapped faces a few days ago, but why stop the swap when so many K-pop idols still have their same old boring (and by boring, I mean beautiful) faces? After some extremely scientific experimentation, I present to you my newest creations- some surprisingly delightful, and some disturbingly hilarious. Behold, The K-pop Swap!

First, the duos:

1. Soyou (SISTAR) & Junggigo

These two worked so well together recording "Some" that they're basically interchangeable.

2. Trouble Maker - HyunA (4Minute) & Hyunseung (Beast)

Flawless duo remains flawless.

3. Jiyeon (T-Ara) & Lee Joon (MBLAQ)

Joonie, how/why so cute?

4. BoA & Taemin (SHINee)

BoA's a little too happy for someone whose hair ended up like...that.

5. IU & Seulong (2AM)

Seriously, the guys always look great in women's formalwear.

And now, the groups:

6. SISTAR19 & Infinite H

*Still screaming about Hoya*

7. 2NE1 & CNBLUE

Rock meets pop, but Min Hyuk isn't a fan. That, or his dress is too tight.

8. Girls' Generation & Super Junior

The big switch. Some made it through unscathed, but many others lost their chins, and possibly their dignity.

Another big thanks to the makers of the iSwap Faces app, as well as to Hoya for making such a bodacious beach babe. Which duo or group do you think made the most seamless swap? Comment below!
