SHINee's Onew has been pretty busy recently due to his participation in the musical "Rock of Ages", held at Olympic Park in Seoul. During the press conference, Onew took particular interest in a reporter's question about celebrities expanding their horizon into various realms of the entertainment industry. He said, "If one person can do all kinds of things, that really gives them an advantage. At first, I wasn't exactly supportive of singers taking on acting roles, but now I realize that you can really show off your singing skills while acting, like being in a musical." 'Rock of Ages' will continue to run until October 30th, and stars Shin Sung Woo, Ahn Jae Wook, J, Dana, and more. Check out some of the photos below. [gallery]
