Not only did Justin Bieber announce the news of his upcoming North American tour on ‘Ellen’ (airing Wednesday, May 23), he also graced audiences with a performance of his latest single, ‘Boyfriend’ and got his very own graduation ceremony thanks to Ellen DeGeneres.

The 18-year-old superstar wore a navy varsity jacket for the show, which was emblazoned with a “J” on the front and the word “boyfriend” on the back (obviously). The live rendition of the song was aided by a backing track and a coed group of dancers.

Bieber strutted his stuff like a pro, and ventured into the audience to give high fives and connect with fans. Although he offered Beliebers the musical treat and the exciting announcement of his headlining tour, Ellen had a surprise in store for the pop star.

Bieber recently completed home schooling, so the talk show host held a graduation ceremony for the singer. Not only did she give a hilarious commencement speech, but she also gifted The Biebs with a diploma and a custom graduation cap that was designed to keep his famous hair in tact.

Bieber will kick off his 2012-2013 Believe tour on Sept. 29 in Glendale, Ariz., and wrap his run up on Jan. 26 in Miami, Fla. next year.
