Kim Jaejoong recently performed at his 'J-JUN LIVE 2019 ～ Love Covers ～' concert at the Makuhari Messe in Chiba, Japan on November 16 and 17.

During these concerts, the guest accompanist gained attention from the crowd.

Masashi Kuwata, known as Matt Kuwata, son of the famous baseball player, Masumi Kuwata, was this guest. Matt has recently gained attention for having "Barbie doll"-like looks. With his pale skin, blue contacts, and alleged plastic surgery Matt has said that his doll transformation has helped him gain notoriety and taken his modeling career to the next level.

Fans seem to have varied opinions of the model and musician and his looks. But Jaejoong showed his support to Matt during the concert, praising his skills as a musician, and thanked him for playing the piano for his concert.
