Both Han Hye Jin and Jeon Hye Bin are in their 30's, but you wouldn't know it from looking at their photos! The two lovely ladies recently snapped a vacation selfie from Europe that would have their fans rubbing their eyes at their youthful looks.

"With Hye Jin unnie in London <3" Jeon Hye Bin posted to her Instagram earlier today. It looks like the two same-aged friends (both are 31 years old) are having some fun in England!

If you didn't know their ages, how old would you think they were? Mid-twenties is our guess!
