Currently watching this week's VS ARASHI & hilariously , Ken was mentioned LOL
Turns out Ken is friends with Kondo Haruna who's 1 1/2 of Harisenbon female comedian duo and she said she went Karaoke with Ken before besides having a meal together
And guess what song Ken sung during the Karaoke session ?
And yes Ken did the same dance moves he did in the POP STAR PV which made Haruna cringe somewhat xD
