On the latest episode of JTBC’s “Hyori’s Homestay 2,” Girls’ Generation’s YoonA, Lee Hyori, Park Bo Gum, and Lee Sang Soon had fun with a face-swapping photo app!

During the April 8 broadcast of the reality show, the four stars enjoyed an afternoon off by relaxing at a cafe together. YoonA and Lee Hyori decided to pose for a face-swap photo, with Lee Sang Soon and Park Bo Gum marveling at the results. Lee Sang Soon was particularly surprised by the two singers’ unexpected resemblance, asking incredulously, “Is this with their faces swapped?”

Park Bo Gum commented, “They both look pretty,” while Lee Sang Soon remarked, “It almost looks like they didn’t switch [faces].” After seeing Lee Hyori’s facial features with her own bob haircut, YoonA told her, “Unnie, I think you’d look pretty with short hair as well.”

YoonA then took a face-swap selfie with Park Bo Gum and Lee Sang Soon, and the three couldn’t stop laughing at how hilarious YoonA looked with Lee Sang Soon’s face on her body.

“Hyori’s Homestay 2” airs on Sundays at 9 p.m. KST.
