f(x)‘s Sulli took an adorably goofy selca with her fellow ‘egg’ friend!

She posted a photo with KARA‘s Jiyoung onto her me2day and wrote, “The egg~ is here!” The pair are smiling brightly at the camera, both making unique aegyo faces.

The two are well-known to be very close friends, and fans should know that Sulli’s ‘egg’ refers to the fact that she calls Jiyoung ‘egg whites’ and that Jiyoung calls Sulli ‘yellow yolk.’ With both combined, they create ‘the egg.’

Fans commented, “94-line friends >_< Cute and pretty,” “Cute, Sulli! You are the prettiest,” and more.
