Justin Bieber has joined US Vice President Joseph Biden, Prince William and Kate Middleton and Oprah Winfrey on Glee's Colin Firth, Bruno Mars, as consisting of, "artists and activists, reformers and researchers, heads of state and captains of industry. Their ideas spark dialogue and dissent and sometimes even revolution."

Writing for the magazine, Justin's friend and mentor Usher had this to say about the Biebster:
"From the minute I met Justin, I knew this kid possessed a certain confidence that only a star could have.
"He was born a star. He knew what he wanted to accomplish; all he had to do was get everyone else to believe it. Now, looking back at his incredible run, the reality of who he is and what he's accomplished far exceeds anybody's expectations of him.
"What's interesting and will keep the world watching is that at the same time he's having this incredible success, he's like any other kid living a normal life."
Writing about her Glee co-star Chris Colfer, Dianna Agron said that he, "lives by extreme truth, speaking out against the epidemic of bullying that he, too, faced in high school. The honesty that he infuses into his 'Glee' character, Kurt, leaves you reeling."
Rapper B.o.B also wrote about his Nothin' On You pal Bruno Mars, saying that the singer/songwriter "has a musicality, a presence in his voice that I've never heard from anyone else."
