Singer John Park might have had a slip-up on the July 18 airing of JTBC's 'Please Take Care of my Refrigerator'!

On this day, he said, "I used to make steak for my friends or for my former girlfriend.  I'm confident when it comes to cooking steak."  MC Kim Sung Joo said, "Did your past girlfriend go to your house?" and he replied, "In the past," unable to hide being taken aback.

MC Ahn Jung Han then said wittily, "These days, you must go eat at your girlfriend's house," and Kim Jun Hyun added, "You guys are like the city investigation squad." Kim Sung Joo said, "Just wait 'til the steak comes out.  We can't protect you."

The MCs went through his fridge for a while, and upon seeing the salmon, chicken breast, and more, Ahn Jung Hwan said, "Your girlfriend must be dieting lately," to which John Park replied impulsively, "Yes," and was again unable to hide how taken aback he was.

He quickly explained with, "I misheard you.  I thought you asked if I was dieting," making everyone laugh.  Do you buy it?
