J-pop star Nakashima Mika (27) has a new man in her life, according to today's issue of weekly women's magazine "Josei Seven." The singer lives in the same apartment building as guitarist Tanaka Yoshito (36), and last week they were spotted dining with Nakashima's mother. The couple are believed to have started dating last summer. Nakashima's management agency refused to comment on the story, saying that it was a private matter.
