Who knew After School's Nana and SISTAR's Dasom were such good friends?

On March 13, Nana posted a collage of photos of the two on her Instagram, with the caption, "With Dasom, who I like because she's ugly. Wow, so ugly. kekekekekekekeke. #dasom #nana #nasom #date #apgujeong #iloveyou #i'llbringmywalletnexttime #you'rereallyugly".

We're sure Nana doesn't mean Dasom is actually ugly, and it just goes to show how close the two must be to be able to joke like that.

The two idol stars seem to be wearing minimal makeup and look like any two regular, albeit very pretty, friends hanging out and taking selcas.
