Heechul poses with f(x) at Music Core backstage

Just like yesterday's picture with fellow Super Junior member Donghae and f(x)'s Sulli, Heechul continues to keep fans in the loop with more pictures with f(x). The pictures were uploaded earlier today while they were waiting for Music Core to begin live broadcast. The first picture (at the top) was taken with all the f(x) members minus Amber who I assume is taking the picture as Heechul wrote, "With f(x), the hottest thing right now." And in the second picture with Amber, he wrote, "I want to hit Amber everytime I see her because she looks like Donghae, but she's actually nice." I hope Donghae has insurance. Watch their NU Abo and Bonamana performances if you haven't. Many thanks to MaknaeHeaven for the tip.
