Bieber fever reached a whole new level in New York City Friday morning (Jun 15) when over 8,000 Beliebers — some in tears — packed into the Rockefeller Center to watch Justin Bieber perform a free concert on NBC’s “Today” Show.

The 18-year-old Pop star treated his fans to a medley of songs, including his latest singles “Boyfriend” and “All Around the World,” and his most well-known hit single “Baby.”

Bieber also brought out rapper Big Sean to perform their collaboration single “As Long As You Love Me.”

After the concert, Justin wrote on his Twitter account:

“@todayshow thanks for having me and thanks for letting me do some extra songs for the fans … Shoutout to @bigsean for coming thru! #BELIEVE.”

Justin Bieber’s new album “Believe” hits stores this coming Tuesday (Jun 19)
