Taecyeon recently revealed that a member of 2PM has a crush on f(x)'s Krystal! On the upcoming July 26th broadcast of SBS's 'Strong Heart', Taecyeon will make a guest appearance to promote 2PM's latest album, 'Hands Up'. While on set, he shared a story of a time he once asked Krystal to feature in one of their songs. He stated, "At that time, the 2PM members thought long and hard about who we'd like to ask to feature in our song... While all chose Krystal, Junho was the most assertive and vocal in choosing her." Meanwhile, Krystal - who also made a guest appearance - shared a story about her abs. She said, "Out of all the members of f(x), I've had an instance when my outfit exposed my body... I don't pay attention to my abs, however, someone took a photo while I was dancing on stage and called it '11 abs [abs that resemble the numbers '11'].' I was surprised the media picked up on it." Later, Krystal shared her routine exercise for her abs and also talked about maintaining a healthy body. Check out their stories in full when the episode airs later tonight.
