INFINITE's Sung Jong knows G.NA's body dimensions?

INFINITE's Sung Jong recently made an awkward confession that he knows the exact body dimensions of singer G.NA. On this week's episode of "Bloody Ties" on the E channel, members of INFINITE participated in a quiz where they had to guess the correct celebrity based on the described body dimensions. Awkward enough, when MC Kim Gook Jin asked, "Height of 168cm, weight of 47kg, slender size of 44 and contrasting D cup, the singer is�?" Sung Jong was quick to correctly shout the answer, "G.NA". In shock, fellow INFINITE members began to tease him and ask, "You're so young, how do you even know G.NA's breast size?" to which Sung Jong confessed, "I know because she's a close nuna of mine." The full episode is set to broadcast on July 21st. Source: Star Today via Nate
