2AM's�Jo Kwon is facing some heat for mistakenly introducing rookie group B1A4 as "B1F4". On June 19th, the "Inkigayo" MC stated:

"Next on stage we have B1F4!"

The group's name, 'B1A4', was created in accordance to the members' blood types, and Jo Kwon had simply confused the letter "A" with the letter "F". After the broadcast, Jo Kwon tweeted,

"During 'Inkigayo' I mistakenly called B1A4 B1F4. I genuinely apologize to B1A4 and B1A4 fans. In the future, I will strive to do my best."

In response to Jo Kwon's tweet, B1A4's leader Jinyoung tweeted back,

"No, Senior Jo Kwon. Thank you so much for the encouragement you've given us. We will try our hardest."

Fans from both camps were amused to see such warm interactions between industry seniors and juniors. Source & Photo: Newsen via Nate
