Park Jung Hyun and Bobby Kim get adorably friendly on 'Radio Star'

There was some romantic energy flowing between singers Park Jung Hyun and Bobby Kim recently.

During the July 25th broadcast of MBC's 'Radio Star', the two appeared to be extra-friendly and were suspected of possibly being romantically interested.

Telling stories about one another, the two could not stop smiling throughout the shoot, and the emcees' suspicions only grew after fellow guest Psy put on his performance.

After watching his mini stage, Park Jung Hyun praised Psy's performance saying, "Your facial expressions were fabulous."

This caused Bobby Kim to blurt, "Facial expressions?", and the emcees not missing a beat had asked if he was jealous. Bobby Kim honestly answered, "A little," and looked upset as he added, "She didn't say that to me."

But in an effort to comfort him, Park Jung Hyun remarked, "I say it to you all the time," drawing much attention from viewers and fans.
