On the December 1 airing of JTBC's new show 'Please Take Care of my Refrigerator', six of Korea's top chefs once again took ingredients from rising foreign star's refrigerators to create delicious dishes that will win over the star's taste buds. On this week's episode, the show featured rising foreign stars, Sayuri and M.I.B's Kangnam.

Sayuri revealed that she and Kangnam were once very close friends who used to call each other every night. However, once Kangnam started gaining popularity, he stopped answering her calls.

She said, "I'm jealous now that Kangnam is popular. We used to be really close but after he started gaining popularity, he stopped contacting me. Before he got popular, we called one another every night, but he doesn't answer his phone calls." 

Kangnam then responded, "The shows that I'm on are reality shows, so we film for 24 hours. If I try to call, then it would be around 2 to 3 AM." 

When Sayuri asked, "Why don't you call me in the afternoon," Kangnam answered frankly, "Aren't you sleeping around then," drawing laughter from the crowd.
